  • He used seven variables at a time: 3 fixed regressors (life expectancy in 1960, primary school enrollment in 1960, and log GDP per capita in 1960), 3 rotating regressors, and the regressor that he's testing (plus a constant, of course).

  • The only non-trivial difference from their study and what I outlined is that I forgot to say to include income as a regressor, an unfortunate oversight by me.
