| Oct 2, 2019 at 8:10 | comment | added | Richard Hardy | Since I do not know (multinomial) logistic regression well, I am not really sure what the fitted probabilities $\hat p_0$ are and whether they constitute a sensible estimate of true probabilities (hence the quotation marks for "estimated expected loss"). I have a gut feeling I might be ignoring the prevalence of each class (sort of the prior which I do not have) and perhaps implicitly assuming uniform class prevalence or something like that. | |
