Therefore when I want to estimate the system in a panel data using industry and year fixed effects ( data has fixed rather than random effects, tested before) , I use the following command:The first is implemented by xttest0 in Stata (and in R in plmtest of package plm). The second in Stata by hettest (and in R in bptest of package lmtest) and - I believe - cannot readily be applied to panel models. The 2nd webpage seems to confuse both tests/use cases.getting started with Stata.
