ISyE7406 – HOMEWORK 4 
Spring 2023 
1. Introduction 
In this homework, we will examine how various local smoothing methods estimate the 
“Mexican hat function” at various points in the interval [-2π, 2π]. Using these methods, 
we will be able to better understand how bias, variance, and mean square error of these 
estimators perform given different spans, bandwidths, and local smoothing parameters. 
2. Exploratory Data Analysis 
The Mexican hat function is defined in the range [-2π, 2π...
Introduction 
Work with “fat” data set and apply 7 linear regression models to the data set. For each model, find out 
the testing error. Since the data set is small, apply Monte Carlo Cross Validation to all the models and 
find out the average Testing error for each model after 100 loops. 
Exploratory Data Analysis 
The “fat” data set has 252 observations and 18 variables. The first column “brozek” is the dependent 
variable representing the percentage of body fat. The rest 17 vari...

PLS Regression? 
The choice of k depends on the application and can be chosen by the 
cross validation 
Correct! 
The choice of k should be as large as possible, say, k=p. 
The choice of k should be a small number such as k=2,3 or 5.

In the linear regression model , the 
Laplace Prior on yields the estimator of the form 
LASSO Correct!

2 
Introduction 
The objective of this assignment is to study how well three distinct local smoothing techniques (LOESS, 
Nadaraya-Watson (NW) kernel smoothing, and Spline Smoothing) perform on a simulated additive noise model. 
�� = �(�) + ��, 
Consuming the Mexican Hat function 
�(�) = (1 − �2 
) exp(−0.5�2 
), where � � [-2�, 2�]. 
In the additive noise model, the error terms follow a normal distribution with mean 0 and standard deviation 0.2, and ar...
