WebFeb 23, 2024 · I am trying to understand the result of the Frisch-Waugh-Lovell Theorem that we can partial out a set out regressors. The model I am looking at is y = X 1 β 1 + X 2 β 2 + u. So the first step would be to regress X 2 on X 1 : X 2 = X 1 γ ^ 1 + w ^ = X 1 γ ^ 1 + M X 1 X 2. with M X being the orthogonal projection matrix ( M X = I − P X ).

In econometrics, the Frisch–Waugh–Lovell (FWL) theorem is named after the econometricians Ragnar Frisch, Frederick V. Waugh, and Michael C. Lovell. The Frisch–Waugh–Lovell theorem states that if the regression we are concerned with is: where and are and matrices respectively and where and are conformable, then the estimate of will be the same as the estimate of it from a modified regression of the form: WebApply Frisch-Waugh-Lowell theorem twice to get the coefficients associated with the two x’s.

FWL establishes that it is possible to re-specify a linear regression model in terms of orthogonal complements. In other words, it permits econometricians to partial out right-hand-side, or control, variables. This is useful in a variety of settings.
