3) You used both -margins, at()- and -margins, dydx() at()-. My
understanding of the difference after reading your answer is that
-margins, at()- gives the /probability/ of Y==1 at the specified values
of X. Whereas -margins, dydx() at()- gives the /change in the
probability/ of Y==1 from an infintesimal change in X at the specified
values of X. Correct?
Yes, that is right.
(as a side note, I wouldn't have expected weight to predict foreign vs
domestic as well as it does)
Foreign cars were a lot lighter than domestic cars in the late 1970s . . .
