Multiple Regression

Multiple Regression. W&W, Chapter 13, 15(3-4). Introduction. Multiple regression is an extension of bivariate regression to take into account more than one independent variable. The most simple multivariate model can be written as: Y =  0 +  1 X 1 +  2 X 2 + 

Extension to Multiple Regression

Extension to Multiple Regression. Simple regression. With simple regression, we have a single predictor and outcome, and in general things are straightforward though issues may arise regarding outliers and violations of assumptions The basic model is Y = b 0 + b 1 X + e.
