WebLooking to the function itself I realized that NeweyWest actually calls vcovHAC. Empirically the results of coeftest (mymodel, vcov. = vcovHAC) and coeftest (mymodel, vcov. = NeweyWest) are mad different. While vcovHAC is somewhat close to the naive lm results, using NeweyWest all coefficients turn insignificant (tests even close to 1). WebDec 18, 2024 · So the question is why coeftest is giving one result, and summary.felm another. The felm documentation doesn't say how exactly it calculates robust SEs; you might need to check the code or contact the author.
