##### Regression Lab: Spring 2018

We use data collected from Kelly Blue Book for several hundred 2005 used General Motors (GM) cars to explore and develop a multivariate regression model to determine car values based on a variety of characteristics such as mileage, make, model, engine size, interior style, and cruise control. In this lab we learn to look at residual plots to check for model assumptions, namely, heteroskedasticity, normality, and multicollinearity as well as explore techniques for variable selection and transformation of variables ot meet model assumptions.
