Multiple Linear Regression
For convenience of notation, we can define !
"
=1. Thus, we simplify the equation of multiple linear regression as follow.
Equation :
In the multiple regression setting, because of the potentially large number of predictors,
it is more efficient to use matrices to define the regression model and the subsequent
analyses
