What is the equation for T A x?

A T A x = A T b. To solve this normal equations, we first compute the relevant matrices.

Why are polynomial regression equations useful?

a. Polynomial regression equations are useful for modeling more complex curvature in regression equations than can be handled by using the method of transformations.
