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.

Least Square Problem

Examples with Solutions

Example 1 a) Show that the system Ax=B with A=[200112] and B=[103]is inconsistent (system with no solutions). b) Find the least square solution to the inconsistent system Ax=B. c) Determine the least square error given by ||Ax−B|| for the solution found in part b). Solution to Example 1 a) The system of equations to solve may be written in the form...
