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...
