ocw.mit.eduThe proof of Property (1) is simple, but there is some subtlety in even understanding what it means to add two random variables. Recall that the value of random variable is a number determined by the outcome of an experiment. To add X and Y means to add the values of X and Y for the same outcome. In table form this looks like: outcome ω: ω. 1 ...

Lecture 13: Simple Linear Regression in Matrix Format
www.stat.cmu.eduThis is just about tolerable for the simple linear model, with one predictor variable. It will get intolerable if we have multiple predictor variables. Fortunately, a little application of linear algebra will let us abstract away from a lot of the book-keeping details, and make multiple linear regression hardly more complicated than the simple ...
