WebFrisch-Waugh (FW) Theorem Consider a multiple regression that involves two regressors y = b 0 + b 1x 1 + b 2x 2 + u The FW theorem states that bˆ 1 in the multiple regression can be obtained in a two-step procedure: 1.Step I: regress x 1 onto x 2; and save the residual (denoted by ˆr) 2.Step II: regress y onto ˆr Because the residual ˆr ... WebThe idea of orthogonalization is based on a theorem designed by three econometricians in 1933, Ragnar Frisch, Frederick V. Waugh, and Michael C. Lovell. Simply put, it states that you can decompose any multivariable linear regression model into three stages or models. Let’s say that your features are in an X matrix.

WebWe have shown the Frisch-Waugh(-Lovell) theorem. Followers of ECON 4150 spring 2013 will have seen a scalar version of this. The 4150 lecture note is still on that course page.
