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...
