WebThis is an application of the Frisch Waugh Lowell theorem. Greene Chapter 1 goes through the mathy side of things. Berk "Regression Analysis: A Constructive Critique" goes through the intuition side of things in the section about what it really means to hold one variable constant, forget the name of the section though.

WebJun 5, 2013 · The Frisch–Waugh–Lovell (FWL) theorem is of great practical importance for econometrics. 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.
