Regression clustering for panel-data models with fixed effects D. Exactly how large a VIF has to be before it causes issues is a subject of debate. The syntax should look like this in general: reshape long stub, i(i) j(j) In this case, 1) the stub should be inc, which is the variable to be converted from wide to long, 2) i is the id variable, which is the unique identifier of observations in wide form, and 3) j is the year variable that I am going to create – it tells Stata that suffix of inc (i.
