please i would like to ask when we want to check for heteroskedasticity in our model .If in our main model we need to control for YEAR and Industry using code (i.YEAR I.INDUSTRY)
What is the appropriate way to do that (do we need to remove year and industry from our model when we check for heteroskedasticity or we need to keep them i expaln this in regression
