Ordinary least squares, two-stage least squares, Poisson and logit regressions with any number of high-dimensional fixed effects, interactions of fixed effects, varying slopes, weights and iid, heteroskedasticity-robust (HC1, HC2, HC3), multiway-clustered, CRV3, Newey-West, Driscoll-Kraay or Conley standard errors. The formula syntax, arguments, results and methods follow the 'fixest' package and reproduce its estimates. The computations run in a parallel 'Rust' library that eliminates the largest fixed effect exactly and solves for the others by preconditioned conjugate gradient.
