#STAT 159 - fall-2016 Homework 3
This is the repository for Homework 3. In this assignment, I attempted to reproduce multiple regression analysis. More specifically, the idea is to reproduce the analysis from Section 3.2 (page 71 to 82), of Chapter 3:Linear Regression, from the book "An introduction to Statistical Learning" (by James et at) at http://www-bcf.usc.edu/~gareth/ISL/.
I also produce historgrams and scatter plots on each independent variables, as well as the multiple regression plots and correlation matrix.
This assignment is the continuation of W2, where we run our simple regression analysis. More functions and their unit tests will be created throughout this homework.
The structure of this homework is as followed.
