But what if we wanted to calculate the EMMs for both foreign and domestic vehicles, while treating rep78 as balanced? We would put foreign in our marginslist like so: . margins foreign, asbalanced Adjusted predictions Number of obs = 69 Model VCE: OLS Expression: Linear prediction, predict(...

but require much larger sample sizes to do so. When error terms are serially correlated, theGauss–Markov theoremassumptions are violated, meaning OLS is no longer the Best Linear Unbiased Estimator
more unified way to view these estimators. In OLS, identification can be said to flow from the assumption that the regressors are orthogonal to the errors; in other words, the inner products, or moments of the regressors with the errors are set to 0. Likewise, in the more general...
We conducted OLS estimations where Attractiveness (relative attractiveness) is the dependent variable and racers' dum- mies are independent variables. Its R2 is about 0.70, which is very high. This means that relative attrac- tiveness is strongly correlated with absolute attractiveness, such that ...

McFadden’s R2 is analogous to the OLS R2 where the log likelihood value for the null model replaces the total sum of squares and the log likelihood value for the unrestricted model replaces the residual sum of squares. An increase in the McFadden statistic indicates better model fit [62]....
