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. http://www.personal.rhul.ac.uk/uhte/006/ec5040/FrischWaugh.pdf research detect license plate with cnn
