7 - Linear Transformations
www.ms.uky.eduIn linear algebra we call these functions or maps linear transformations. Definition Let V and W be vector spaces over the real numbers. Suppose that T is a function from V to W, T:V 6 W. T is linear (or a linear transformation) provided that T preserves vector addition

www.stat.cmu.edulinear 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 version1.

If they are, prove it; if not, provide a counterexample to one of the properties: (a) T : R2!R2, with T x y = x+ y y Solution: This IS a linear transformation. Let’s check the properties:
