I tried to do heteroskedasticity test for panel-level data by using the commands from the site mention below. But unfortunately, it showed some subcommand error. But after that, i used the same pooled regression test and got a different result for the same data than the previous result. I checked it many times and compare with previous log file result but its different. Can anybody tell why it's different and how I can change it?
