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:

The fact that can be calculated by regressing on is often called Frisch-Waugh-Lovell theorem. Example: demeaned regression. As an example, we discuss the so-called demeaned regression. Suppose that the first column of is a vector of ones (corresponding to the so-called intercept). We partition the design matrix as where …

The first few times I saw the Frisch-Waugh-Lovell theorem in practice, I did not appreciate it. However, I’ve become a pretty big fan of it—FWL is helpful in a number of ways. 7 The theorem can give you some interesting insights into what is going on inside of OLS, how to interpret coefficients, and how to implement really messy regressions.
