We see a few categories with unbalanced data like Churn,
SeniorCitizen, PhoneService.
It is possible that Random Forests or XGBoost work better for this task since are often better suited for unbalanced datasets.
Correlation of Numerical Variables
cor(df[, sapply(df, is.numeric)])## tenure MonthlyCharges TotalCharges

## TotalCharges 0.8258805 0.6510648 1.0000000With the few non-categorical variables that we have, we can observe
the obvious relationship that tenure has with
TotalCharges, as well as Monthly and Total Charges
Churn Rates across different customer segments
Churn based on Gender
ggplot(df, aes(x = gender, fill = Churn)) +
geom_bar(position = 'dodge') +
geom_text(stat = 'count', aes(label = after_stat(count)),
position = position_dodge(width = 0.9),
vjust = -0.3, size = 3) +
labs(title = 'Churn Rates across Gender',
x = 'Gender',
y = 'Churn Count') +
theme_minimal()
Churn rates across gender don’t seem to show any
significant differences.
Churn based on SeniorCitizen
ggplot(df, aes(x = SeniorCitizen, fill = Churn)) +
geom_bar(position = 'dodge') +
geom_text(stat = 'count', aes(label = after_stat(count)),
position = position_dodge(width = 0.9),
vjust = -0.3, size = 3) +
labs(title = 'Churn Rates across Senior Demographics',
x = 'Senior Citizen',
y = 'Churn Count') +
theme_minimal()
We can see a big class imbalance in SeniorCitizen, which
likely means that most of our customers aren’t seniors.
We are able to see that almost half of our
SeniorCitizens are churning. This means that a bigger
proportion of our SeniorCitizen class is churning.
Churn based on Partner
ggplot(df, aes(x = Partner, fill = Churn)) +
geom_bar(position = 'dodge') +
geom_text(stat = 'count', aes(label = after_stat(count)),
position = position_dodge(width = 0.9),
vjust = -0.3, size = 3) +
labs(title = 'Churn Rates based on Partner',
x = 'Partner',
y = 'Churn Count') +
theme_minimal()
When Partner is ‘No’ we have a higher proportion of
people churning than then it is ‘Yes’.
This could be interpreted as a negative association with
Churn.
People with Partners have a lower proportion of
churning.
Churn based on whether the customer has dependents or not
ggplot(df, aes(x = Dependents, fill = Churn)) +
geom_bar(position = 'dodge') +
geom_text(stat = 'count', aes(label = after_stat(count)),
position = position_dodge(width = 0.9),
vjust = -0.3, size = 3) +
labs(title = 'Churn Rates based on whether Customer has Dependents',
x = 'Dependents',
y = 'Churn Count') +
theme_minimal()
Having Dependents seems to have a negative association
with Churn.
People with Dependents have a lower proportion of
churning.
Plots that separate Churn
ggplot(df, aes(x = Churn, y = tenure)) +
geom_boxplot() +
labs(title = 'Tenure affects Churn probability',
x = 'Churn',
y = 'Tenure (months)') +
theme_minimal()
tenure seems to be a good separator for
Churn. It is possible to see that a lower
tenure is associated with higher probability of
churning.
ggplot(df, aes(x = Churn, y = MonthlyCharges)) +
geom_boxplot() +
labs(title = 'Monthly Charges affecting Churn',
x = 'Churn',
y = 'Monthly Charges') +
theme_minimal()
Our boxplot doesn’t show much separation in
Monthly Charges when comparing to Churn.
It seems like higher Monthly Charges do have an
association with Churn.
ggplot(df, aes(x = Churn, y = TotalCharges)) +
geom_boxplot() +
labs(title = 'Total Charges has almost no separation when classifying Churn',
x = 'Churn',
y = 'Total Charges') +
theme_minimal()
Seems almost irrelevant to compare TotalCharges to
Churn, since we already have a small idea that a longer
tenure is positively associated with not churning.
The plot does show a small cluster of outliers with high
TotalCharges in the ChurnYes. This could be
interesting because that must mean we are losing valued customers with a
high tenure.
#subset Churn == Yes

Key Questions
Do certain demographics have a higher churn rate?
Based on our plots, it appears that Senior Citizens do have a higher
churn rate. To prove this, we will use chi-square tests of independence
between our categorical demographic variables and
Churn.
Our null hypothesis states that Churn is independent of being a Senior Citizen. (Gender, Dependents)
Alternative hypothesis that Churn is related to being a Senior Citizen.
Chi-square tests
#chi-square test for SeniorCitizen
chisq.test(table(df$SeniorCitizen, df$Churn))##
## Pearson's Chi-squared test with Yates' continuity correction
##
## data: table(df$SeniorCitizen, df$Churn)
## X-squared = 158.44, df = 1, p-value < 2.2e-16p-value is lower than 0.05 so we reject the null hypothesis
There is strong evidence that being a
SeniorCitizen is associated with churn.
#chi-square test for Gender
chisq.test(table(df$gender, df$Churn))##
## Pearson's Chi-squared test with Yates' continuity correction
##
## data: table(df$gender, df$Churn)
## X-squared = 0.47545, df = 1, p-value = 0.4905p-value is higher than 0.05 so we fail to reject the null hypothesis.
There is no significant evidence that gender is
associated with churn.
#chi-square test for Partner
chisq.test(table(df$Partner, df$Churn))##
## Pearson's Chi-squared test with Yates' continuity correction
##
## data: table(df$Partner, df$Churn)
## X-squared = 157.5, df = 1, p-value < 2.2e-16#chi-square test for Dependents
chisq.test(table(df$Dependents, df$Churn))##
## Pearson's Chi-squared test with Yates' continuity correction
##
## data: table(df$Dependents, df$Churn)
## X-squared = 186.32, df = 1, p-value < 2.2e-16Based on the chi-square test p-value lower than 0.05, we reject the
null hypothesis and assume that both Partner and
Dependents are associated with churn.
As we identified from our plots, Partner and
Dependents seemed to have a negative association with
Churn.
What factors influence customer churn the most?
In order to account for possible multivariate effects, we are not going to run Chi-square, ANOVA, or t-tests.

## [1] "Chi-square for Churn"
## [1] 0Based on our hypothesis tests, we want to reject null hypothesis to suggest strong evidence that the variables are associated with Churn. The lower the p-values, the stronger the evidence. Below are our most significant variables:
- Contract (p-value of 7.33e-257)
- Tenure (p-value of 2.35e-254)
- OnlineSecurity (p-value of 1.4e-180)
- TechSupport (p-value of 7.41e-180)
- InternetService(p-value of 5.83e-159)
These five variables show the strongest univariate association with
Churn. However, it is important to note that these tests do
not account for multivariate effects. One variable could in theory
explain the same amount of variance in Churn as another,
making one of the two statistically insignificant. Therefore, we will
refrain from making an assumption about which factors influence customer
churn the most until we fit them on predictive models. By building
models such as logistic regression, we can interpret the coefficients to
see the direction and strength of each variable’s effect. Similarly,
Random Forests can provide a ranked feature importance that takes into
account complex, nonlinear interactions and multicollinearity.
Are customers with long-term contracts less likely to leave?
For this question, we can use another Chi-square test to assess whether there’s a statistically significant association between contract type and churn status.
Null hypothesis: Contract type does not have a statistically
significant association with Churn
Alternative hypothesis: Contract type and Churn have a
statistically significant association.
chisq.test(table(df$Contract, df$Churn))##
## Pearson's Chi-squared test
##
## data: table(df$Contract, df$Churn)
## X-squared = 1179.5, df = 2, p-value < 2.2e-16We reject the null hypothesis. Our p-value lower than 0.05 suggests
that there is a significant association between contract type and
Churn. We can assume that at least one contract
type has a different churn rate compared to the others.
We can create a bar plot to visualize these differences.
ggplot(df, aes(x = Contract, fill = Churn)) +
geom_bar(position = "fill") +
labs(title = "Churn Proportions by Contract Type",
y = "Proportion",
x = "Contract Type") +
theme_minimal()
It does in fact seem like month-to-month has a much bigger difference in people who churned.
Which service do most customers subscribe to?
First we need to create a dataframe that contains the counts of all customers subscribed to certain services.
service_vars <- c('PhoneService', 'OnlineSecurity', 'OnlineBackup',
'DeviceProtection', 'TechSupport', 'StreamingTV', 'StreamingMovies',
'MultipleLines')
service_counts <- sapply(service_vars, function(var){
sum(df[[var]] == 'Yes', na.rm = TRUE)
})
#InternetService isn't a yes/no so we do that separately
InternetService_counts <- sum(df$InternetService == 'DSL', na.rm = TRUE) +
sum(df$InternetService == 'Fiber optic', na.rm = TRUE)
#bind it to service_counts
service_counts <- c(service_counts, InternetService = InternetService_counts)
#turn it to a dataframe
service_counts <- data.frame(
service = names(service_counts),
count = service_counts
)ggplot(service_counts, aes(x = reorder(service, -count), y = count)) +
geom_bar(stat = 'identity', fill = 'lightblue') +
geom_text(aes(label = count),
position = position_dodge(width = 0.9),
vjust = -0.3, size = 3) +
labs(title = 'Most subscribed services',
x = 'Service',
y = 'Number of Customers') +
theme_minimal() +
theme(axis.text.x = element_text(angle = 45, hjust = 1))
From our plot, we can see that PhoneService is the
service that most customers subscribe to. InternetService
is second. We expected this since it appears that the company does not
sell StreamingMovies or StreamingTV unless
they have the InternetService, just as they can’t sell
MultipleLines if the customer doesn’t have
PhoneService.
Can we build a predictive model to identify customers at risk of churning?
For the sake of simplicity, we will adapt our dataframe so that the
categorical variables with 3 levels will be reduced to 2. Since we are
only interested in Churn, having a ‘No internet service’
level will just be treated the same as No. Same will apply for ‘No phone
service’.
service_vars2 <- c('OnlineSecurity', 'OnlineBackup',
'DeviceProtection', 'TechSupport', 'StreamingTV', 'StreamingMovies',
'MultipleLines')
for(var in service_vars2) {
df[[var]] <- as.character(df[[var]]) #temporary make it character
df[[var]][df[[var]] %in% c('No internet service', 'No phone service')] <- 'No'
df[[var]] <- as.factor(df[[var]]) #convert back to factor
}InternetService also has a different reference level
than all other categorical variables so for better interpretability we
shall re-level.
#set 'No' as reference level for InternetService
df$InternetService <- relevel(df$InternetService, ref = 'No')Train-test split
set.seed(42)
train_index <- createDataPartition(df$Churn, p = 0.7, list = FALSE)
train_data <- df[train_index, ]
test_data <- df[-train_index, ]
#validation set for threshold adjusting in log_model
train_val_index <- createDataPartition(train_data$Churn, p = 0.8, list = FALSE)
validation_data <- train_data[-train_val_index, ]
train_data <- train_data[train_val_index, ]Logistic Regression
Based on our analysis of factors influencing Churn, we
can expect Contract and tenure to be
significant, even with the multivariate effects since they stood out
with the lowest p-values by a large margin.
We also know that it is likely one of our numerical variables to have a high VIF, because we saw previously that they had a strong positive correlation with one another. This means we must check for VIF.

## In this scenario, we are obviously prioritizing Sensitivity.
Predicting no but the customer churns would result in one less customer and loss of money.
Predicting yes but the customer stayed would result in a small cost of offering an incentive.
Due to this, we will find a better threshold to find an optimal trade-off.
roc_obj <- roc(test_data$Churn, log_preds)## Setting levels: control = No, case = Yes## Setting direction: controls < casesauc(roc_obj)## Area under the curve: 0.8552Our model has a good discriminative power. It can distinguish between churn and non-churn about 85.5% of the time.
Threshold Adjusting
Since we are adjusting the threshold, we need to utilize our validation set because adjusting the threshold on the test set would mean that we are tailoring our model to the ‘unseen’ data.
First we make a set of predictions on the validation set

## With this new threshold, we trade off some specificity, but increases our sensitivity by a solid margin.
Without any information on the expenses that a retention strategy would incur per customer, it’s difficult to quantify if a higher accuracy model or a more balanced sensitivity-specificity model would result in lower losses.
Based on the average MonthlyCharges of $68.80, we would
like to believe that our model with the adjusted threshold would result
in higher profits for the company. Unless the cost of acting on
non-churners is really high, Model 2 is smarter business.

For this simple model, we will use just some standard parameters. We will use this as a benchmark for our Fine-tuned model with a hyper grid.
We will also use our best 8 predictors based on the importance that was shown in our Decision Tree model.

Based on our plots, we can see that certain variables have a higher
importance specifically for predicting ChurnYes, but lower
importance for predicting ChurnNo.
For example, for ChurnYes, Contract has the
highest importance, while for ChurnNo it has a negative and
lowest importance.
PDP plots
plot.variable(rf_model, partial = TRUE, plots.per.page = 1)
Based on our PDP plots, we can see that as tenure
increases, so does the probability of ChurnNo. We already had an idea of
this based on our logistic regression coefficient.
TotalCharges is a different story. It reveals a clear
relationship with customer churn, as customers with higher
TotalCharges have a higher probability of staying. This
makes sense since this variable is lowly correlated with
tenure. We also see a bit of ups and downs, but after
peaking we see diminishing returns.
It is also possible to appreciate how all of our categorical variables and their levels affect the probability of not churning.

## XGBoost Model
Variable Selection (RFE)
Using random forest again, we use variable importance to get an idea for most important variables to include in our XGBoost.

set.seed(42)

#best variables
rfe_result$optVariables## [1] "tenure" "MonthlyCharges" "TotalCharges" "InternetService"
## [5] "Contract" "OnlineSecurity" "TechSupport" "PaymentMethod"
## [9] "PaperlessBilling" "MultipleLines" "OnlineBackup" "StreamingMovies"
## [13] "StreamingTV" "Dependents" "Partner"XGBoost recognizes these variables as the most important in that
order. We know MonthlyCharges and TotalCharges
are correlated. Since we have solid computational power, we will use all
the features available to us, we will see feature importance of the
models, and see the results. Since XGBoost will automatically only use
relevant variables, and we are trying to maximize performance of our
model, we won’t that it’ll take longer to fit.
