Robust Standard Errors in STATA

”Robust” standard errors is a technique to obtain unbiased standard errors of OLS coefficients under heteroscedasticity. In contrary to other statistical software, such as R for instance, it is rather simple to calculate robust standard errors in STATA. All you need to is add the option robust to you regression command. That is:

regress y x, robust

Below you find a working example that shows you how the option works

*create an interaction term
gen interaction = lag_calories*lag_cycling

*OLS with heteroscedasticity consistent standard errors
regress weight lag_calories lag_cycling interaction, robust
