(1) Data Preparation.

Data that we use is data College from package ISLR2. This data loads characteristic from \(777\) university in USA based on the information in \(1995\). Response variable that will be used is Outstate (tuition fee for students who came from out of state where the university exist). Here are some data preparations that will be done.

  • Checking Available Status of Package ISLR2.
if(!requireNamespace("ISLR2",quietly = T)){
  stop("Install package ISLR2 firstly.")
}
  • Loading Data empiric_data.
empiric_data <- ISLR2::College

str(empiric_data)
'data.frame':   777 obs. of  18 variables:

  • Changing Value of Variable Private.

Change value of variable Private with rule: \(0\) for “No” (not private school) and \(1\) for “Yes” ( private school). After changing the value of variable Private, change class of variable Private into integer. So through this process, we have changed variable Private to be a numeric dummy variable.

empiric_data <- empiric_data %>%
  dplyr::mutate(
    Private = ifelse(Private == "No",0,1)
  ) %>%
  dplyr::mutate(Private = 
           as.integer(Private))

class(
  empiric_data$Private)
[1] "integer"
  • Checking Dimension of data empiric_data.
dim(empiric_data)
[1] 777  18

Dimension of empiric_data is \(777\) and \(18\). It means data empiric_data consists of \(777\) observations and \(18\) variables.

  • Checking NA Value.
as.matrix(
  colSums(is.na(empiric_data))
  )
            [,1]
Private        0
Apps           0
Accept         0
Enroll         0
Top10perc      0
Top25perc      0
F.Undergrad    0
P.Undergrad    0
Outstate       0
Room.Board     0
Books          0
Personal       0

Terminal       0
S.F.Ratio      0
perc.alumni    0
Expend         0
Grad.Rate      0

From NA value checking process above we can know that there is no any NA value in data empiric_data.

From this checking we can know that in ultimate cicumstance data empiric_data has \(17\) numeric and \(1\) integer variables.

  • Dividing Data empiric_data Into Training and Testing Data.

Divide data empiric_data into \(80 \: \%\) training data and \(20 \: \%\) testing data.

set.seed (2026)

# train_index
train_index <- sample.int(
  n = nrow(empiric_data),
  size = floor(
    0.8 * nrow(empiric_data)
  )
)

# empiric_data_train
empiric_data_train <- 
  empiric_data[
    train_index,,drop = FALSE
  ]

# empiric_data_test
empiric_data_test <- 
  empiric_data[
    -train_index,,drop = FALSE
  ]

# table of division result
data.frame(
  dataset = c(
    "whole data",
    "training data",
    "data"
  ),
  observation = c(
    nrow(empiric_data),
    nrow(empiric_data_train),
    nrow(empiric_data_test)
  ),
  variable = c(
    ncol(empiric_data),
    ncol(empiric_data_train),
    ncol(empiric_data_test)
  )
  
)

    • Interpretation.

      From the summary of model basic_l_reg above we can know several things like these.

      • Model basic_l_reg produces R-squared value as big as \(0,768\) and Adjusted R-squared value as big as \(0,7614\). It means that model basic_l_reg is able to explain around \(76,8 \: \%\) variations of response variable (Outstate) inside the data which is used for estimation.

      • There are eight predictor variables who do not have significant relation with variable Outstate, it can be shown from their \(Pr(>|t|)\) which are \(\geq \, \alpha \,(0,05)\), those are Enroll, Top25perc, F.Undergrad, P.undergrad, Books, Personal, PhD, and S.F.Ratio.

      • There are nine predictor variables who have significant relation with variable Outstate, it can be shown from theirs \(Pr(>|t|)\) which are \(< \, \alpha \, (0,05)\), they are Private, Apps, Accept, Top10perc, Room.Board, Terminal, perc.alumni, Expend, and Grad.rate.

      From the things that we have declared before, at a glance appears intuition to use only predictor variables who have significant relation with response variable Outstate . But need to be noticed: that intuition is not always right. Let us overview the multicolinearity existence in model basic_l_reg.

      as.matrix(vif(basic_l_reg))

      By using threshold \(VIF \leq 10\) , we can obtain four predictor variables with multicolinearity issues, those are Apps, Accept, Enroll, and F.Undergrad. Since there are multicolinearity issues, then partial effects of those four variables may be obscured, so the partial test result as like as what we have obtained before may be not fully right. Be noticed that there are two of those four variables which are parts of predictor variables with significant relation with response variable Outstate. Those two variables are Apps and Accept. Since they have the multicolinearity issues, then the significant-relation-with-response-variables status can be doubted, so it will be felt like not-too-right to follow our previous intuition, that is intuition to create a new model using nine predictor variables with significant relation with response variable Outstate. It means that we need other methods for handling this issue, one of them is by doing variable selection.

      From the counting-correlation syntax above we could obtain six predictor variables with highest Pearson correlation coefficient, those are variables Room.Board, Expend, Grad.Rate, perc.alumni, Top10perc, and Private. On the next process, we will use these chosen variables for generating a new linear regression model.

    • Generating Model Using Chosen Predictor Variables.

      Before we generate a new model using those six chosen predictor variables, let us firstly constitute a new formula special to be used in this modelling process.

      # take chosen 
      # predictor variables
      # cor_predictor
      
      cor_predictor <-
        cor_outstate_complete %>%
        dplyr::pull(predictor)
      
      # contitute a new formula
      # special for this 
      # modelling process
      # which covers
      # six chosen predictor variables
      # cor_l_reg_formula
      
      cor_l_reg_formula <- 
        stats::reformulate(
          cor_predictor,
          response = "Outstate"
        )
      cor_l_reg_formula
      Outstate ~ Room.Board + Expend + Grad.Rate + perc.alumni + Top10perc + 
          Private

      After we have defined our special formula cor_l_reg_formula, then we continue to generate a new linear regression model using six chosen predictor variables (Room.Board, Expend, Grad.Rate, perc.alumni, Top10perc, and Private)

      cor_l_reg_model <- 
        lm(cor_l_reg_formula,
           data = empiric_data_train)
      
      summary(cor_l_reg_model)

    • Interpretation.

      From the summary of model cor_l_reg_model above we can know several things like these.

      • Model cor_l_reg_model produces R-squared value as big as \(0,7326\) and Adjusted R-squared value as big as \(0,73\). It means that model cor_l_reg_model is able to explain around \(73,26 \: \%\) variations of response variable (Outstate) inside the data which is used for estimation.

      • All predictor variables who have significant relation with variable Outstate, it can be shown from theirs \(Pr(>|t|)\) which are \(< \, \alpha \, (0,05)\).

      To make sure that previous findings are right, let us overview the multicolinearity existence in model cor_l_reg_model.

      as.matrix(vif(cor_l_reg_model))
                      [,1]
      Room.Board  1.613561
      Expend      2.211906
      Grad.Rate   1.671928
      perc.alumni 1.613796
      Top10perc   2.078388
      Private     1.343791

      By using threshold \(VIF \leq 10\) , we can know that there is no any predictor variables which has multicolinearity issues because their each \(VIF\) value is \(\leq 10\).

      To make sure again findings is really good, let us overview also the heteroscedasticity circumstance in model cor_l_reg_model.

      bptest(cor_l_reg_model)
      
          studentized Breusch-Pagan test
      
      data:  cor_l_reg_model
      BP = 68.407, df = 6, p-value = 8.671e-13

      By using rule: \(p-value\) which must be \(\geq \: \alpha \: (0,05)\) - meanwhile our real \(p-value < 0.05\), then with-a-heavy-heart we will say that residuals as the result as from model cor_l_reg_model is really varied (a.k.a not homogen). Residuals is defined as the difference between actual Outstate value and predicted Outstate value, where predicted Outstate value is obtained by predicting Oustate value using model cor_l_reg_model. Since residuals of cor_l_reg_model is really varied, then may there will be incosistency of prediction results, sometimes predicted values can be close to the actual, but sometimes predicted values can be far from the acutal. It means that our model is not as good as what we thought. Therefore we need to find other (variable selections) methods for giving better findings.

(4). Answers of Analytical Questions.

  • Based on the analysis process that I have done, I found that there are some methods which choose the same predictor combinations, those are:

    • RFE and LASSO lambda.min - choosing 17 predictor variables with same combinations.

    • Backward Elimination and Bidirectional Stepwise - choosing 14 predictor variables with same combinations.

    Additional proof:

# proof that predictor of 
# RFE and LASSO lambda.min
# are same

sort(rfe_predictor) == 
  sort(chosen_lambda_min_table$predictor)
 [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE
[16] TRUE TRUE
# proof that predictor of 
# Backward Elimination and 
# Bidirectional Stepwise
# are same

sort(attr(terms(model_backward),
          "term.labels")) ==
  sort(
    attr(terms(model_stepwise),
         "term.labels")
  )
 [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE
  • Based on the analysis process that I have done, not always when some predictors are eliminated and then RMSE value will descend too. Look at RMSE of LASSO lambda.1se, where its much of predictors (\(14\)) is less than other methods (\(16 \: \& \:17\)) except Pearson correlation (\(6\)), but its RMSE (\(2020.229\)) even more than RFE’s RMSE (\(2004.051\)), where RFE notabene selected much more predictors (\(17\)) than LASSO lambda.1se.

  • Related with chosen predictor variables, if we want to reveal that chosen predictors are important predictors then we have to ensure that :

    • we have identified well the structure of the data,

    • we have applied suitable variable selection method based on our data’s structure,

    • we have ensured that threshold that we used has been adjusted with our data’s condition,

    • we have checked that by using chosen variables for follow-up-analysis, then our model (that we built using those chosen variables) will produce good-even-high accuracy,

    • we have checked that almost or even all required assumptions for follow-up-model (that we built by using those chosen variables) are fulfilled,

    • and also we have checked that the error of follow-up-model (that we built by using those chosen variables) are small enough even very small.

If chosen predictors can fulfill almost-or-all of these requirements, then at that same time we also have obtained enough proof to reveal that the chosen variables are important variables, but it doesn’t justify that other unselected predictors are trully not important/not-bringing-advantages. Other unselected predictors may be not “important” for a certain response variable, because not much “informations” given by these unselected predictors toward this certain response variable; but may be to other response variables these unselected predictors give much more “informations”.
