@IljaK91 regtable() prints the square root of the diagonal of vcov(dfrm::DataFrameRegressionModel) (in case of GLM.jl’s output), or the vcov field of a AbstractRegressionResult (if you use FixedEffectModels.jl). As long as you pass the adjusted vcov matrix in these objects to regtable(), they should print correctly.
Are you adjusting the standard errors yourself, or are you using a package to do it for you? If so, it would be great to support it.
