Solved Consider The Following Data Set Xi 1 2 011 12 Yi Chegg Question: consider the following data set xi | 2 |1 |3 yi |2 | 1 |1 and the model y=ao a1sin (x) in the sense of the least square, which one of the following two choices for the model parameters fits better the data set?. Use 16 digits in your calculations and give the answers with at least 5 significant digits hint:use linearization of the model ao= a1= the model you're trying to fit is a linear model of the form y = a0 a1*x. this is a simple linear regression problem.
Solved Consider The Following Data Set Xi 2 1 3 Yi 2 Chegg Fit by least squares the following data set x = [0.0, 1.0, 2.0, 3.0] and y = [ 1.9, 1.0, 4.1, 4.3] with the model: y = @0 @1 sin (x) @2 cos (x). use at least 5 digits in your answers. Solution: the implementation in r (see appendix) and graphs are attached. it's clear that for k = 1; 3; 5; 7 and 15, the k nearest neighbor has a smaller classi cation error for the testing dataset compared to that of the linear regression.
