Resmapling Method

This exercise is to practise the resampling method in the book Introduction to Statistical Learning with R

Validation Approach

• Get started

# Import library 
library(ISLR); library(ggplot2); library(tidyverse)
# Rename the Auto dataset to df
df<-Auto # You can find out more about Auto data by typing command ?Auto
# Look at few rows of data
head(df)

• Splitting data into training set and test Our goal is to build a simple linear regression to predict mpg using horsepower

# Splitting data 
library(caTools)
sam<- sample.split(df$mpg, SplitRatio = 0.7)
training<- subset(df, sam==T)
test<-subset(df, sam==F)
# Check some info
dim(training); dim(test)

Plotting a scatter plot between mpg and horsepower

plot(df$mpg~df$horsepower, main="Scatter Plot", xlab="Engine Displacement",ylab="Miles per gallon", pch=16, col=4)

Building a simple linear regression

lm1<-lm(mpg~horsepower, data=training)
# Get some statistics 
summary(lm1)

Call:
lm(formula = mpg ~ horsepower, data = training)

Residuals:
     Min       1Q   Median       3Q      Max 
-13.9446  -3.2033  -0.3439   2.7445  16.5099 

Coefficients:
             Estimate Std. Error t value Pr(>|t|)    
(Intercept) 40.727322   0.866767   46.99   <2e-16 ***
horsepower  -0.163649   0.007879  -20.77   <2e-16 ***
---
Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1

Residual standard error: 5.075 on 286 degrees of freedom
Multiple R-squared:  0.6013,    Adjusted R-squared:  0.5999 
F-statistic: 431.4 on 1 and 286 DF,  p-value: < 2.2e-16

Testing our model

# Create a horsepower for prediction from test
t1<-data.frame(horsepower=test$horsepower)
# Predict the horsepower using the model
p1<- predict(lm1,newdata=t1)
# Check the accuracy
mean((test$mpg-p1)^2) # Mean Sum Square is 22.61 

[1] 19.7367

We can get diagnose plots

par(mfrow=c(2,2)) # Create a four row and four column 
plot(lm1)

We see some non-linear in the plot above, and so we should go for non-linear functions

# Using quadratic model
lm2<-lm(mpg~poly(horsepower,2), data=training) 
# Using cubic model
lm3<-lm(mpg~poly(horsepower,3), data=training) 
# Get summary 
summary(lm2)

Call:
lm(formula = mpg ~ poly(horsepower, 2), data = training)

Residuals:
     Min       1Q   Median       3Q      Max 
-14.8986  -2.7058  -0.1013   2.2801  15.7348 

Coefficients:
                      Estimate Std. Error t value Pr(>|t|)

poly(horsepower, 2)1 -105.4052     4.6039 -22.895  < 2e-16 ***
poly(horsepower, 2)2   36.4078     4.6039   7.908 5.79e-14 ***
---
Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1

Residual standard error: 4.604 on 285 degrees of freedom
Multiple R-squared:  0.6731,    Adjusted R-squared:  0.6708 
F-statistic: 293.4 on 2 and 285 DF,  p-value: < 2.2e-16

Check the performance of the two models

# Predicting on the test set
p2<- predict(lm2, newdata=t1) # Predicting for model 2 (quadratic)
p3<-predict(lm3, newdata=t1)
# Get accuracy 
Poly2 <- rep(0,1)
Poly3<-c(0)
for ( i in 1){
  Poly2[i]<-mean((test$mpg-p2)^2)
  Poly3[i]<- mean((test$mpg-p3)^2) 
}
Poly2; Poly3

[1] 13.49963

Examine the diagnose plot, and we see that residuals vs fitted plots look well.

# Create a four window
par(mfrow=c(2,2))
plot(lm2) # It looks well now without much pattern in the model

K-fold Cross validation

Building a simple linear regression model

# Using boot library for this task

# Using leave-one-out cross-validation
set.seed(123)
LONE<-glm(mpg~horsepower, data=df) # Fitting a linear regression using leave one out cross validation
MSE_Lone<-cv.glm(df, LONE) # Caculating the Mean Square error 
MSE_Lone$delta[1] # The mean square error of the model is 24.23

We can fit different polynomial models using LOOCV (leave one out cross-validation)

# Create a for loop for this task
MSE<-rep(0,5) # Create five numbers 0
for ( i in 1:5){
  LOOCV<- glm(mpg~poly(horsepower,i), data=df)
  MSE[i]<- cv.glm(df,LOOCV)$delta[1]
}
MSE # Model accuracy for each polynomal order, starting from 1 to 5
