Multiple Linear Regression Multiple Linear Regression A regression with two or more explanatory variables is called a multiple regression. Random Effects Jonathan Taylor – p. Chapter Introduction is a technique for analyzing multiple regression data that suffer from multicollinearity. In this lab we will look at how R can eliminate most of the annoying calculations involved in a using Chi-Squared tests to check for homogeneity in two-way tables of catagorical data and b computing. When multicollinearity occurs, least squares estimates More information.
