A small note, given that this tutorial was recorded a couple of years ago: if you find problems with heteroscedasticity in your data and decide to use one of the heteroscedasticity-consistent standard error options, select HC3 or HC4, not HC0 as recommended in the tutorial. If this isn’t making any sense to you, it will hopefully become self-explanatory once you reach the relevant section in the tutorial.
