WebExplanation: When running instrumental-variable regressions with the ivregress package, robust standard errors, and a gmm2s estimator, reghdfe will translate vce (robust) into wmatrix (robust) vce (unadjusted). This maintains compatibility with ivreg2 and other packages, but may unadvisable as described in ivregress (technical note). Webmust be specified using vce(vcetype)in the tpmsyntax.

WebApr 2, 2024 · Here are the results in Stata: The standard errors are not quite the same. That’s because Stata implements a specific estimator. {sandwich} has a ton of options for calculating heteroskedastic- and autocorrelation-robust standard errors. To replicate the standard errors we see in Stata, we need to use type = HC1. WebApr 2, 2024 · Stata uses a small sample adjustment for their GLM function, in which the standard sandwich variance (obtained via the vce (robust) command) is scaled according to the sample size and the number of parameters in the model. R uses no such adjustment.
