%description
Implemented is an algorithm to estimate the two-way fixed effect linear
model. The coefficients of interest are computed using the residuals from
the projection of all variables on the two sets of fixed effects. Our
algorithm has three desirable features. First, it manages memory and
computational resources efficiently which speeds up the computation of the
estimates. Second, it allows the researcher to estimate multiple
specifications using the same set of fixed effects at a very low
computational cost. Third, the asymptotic variance of the parameters of
interest can be consistently estimated using standard routines on the
residualized data. Somaini P., Wolak F. A. (2016)
