 description = "Fast high dimensional fixed effect estimation following syntax of the fixest R package. Supports OLS, IV and Poisson regression and a range of inference procedures (HC1-3, CRV1 & CRV3, wild bootstrap, randomization inference, simultaneous CIs, Romano-Wolf's multiple testing correction). Additionally, supports (some of) the regression based new Difference-in-Differences Estimators (Did2s, Linear Projections)."
