WebSep 7, 2024 · If I understand it correctly, if the "robust" and "cluster" options are specified in the xtivreg2 command, xtivreg2 calculates a version of the endogneiety test that is robust to heteroskedasticity and serial correlation within panel groups. I would like to see the exact formula used to calculate the endogeneity test. WebOct 21, 2024 · I can comment on what you did it in Stata. regress, robust is robust in one specific sense only: the standard errors are Huber-White-sandwich standard errors (yet another names exist). Otherwise the coefficients are exactly as OLS yields, as omitting the robust option will show you. WebJun 10, 2024 · 1) under -xtreg- (I assume you're using this -xt- command) both -robust- and -cluster- options do the very same job (as they tell Stata to adopt a cluster-robust standard error); 2) running regressions with different specifications and obtaining different resulst comes with no wonder at all. demonstracije u beogradu 9 mart

WebOct 6, 2024 · For continuous covariates, the conclusions are different. From the literature, two practical considerations arise. First, taking sample size on its own as a criterion is not enough to obtain accurate standard errors in the presence of heteroskedasticity. What matters is the number of observations per regressor.
