When estimating an ordered logistic regression in R using library(MASS)::polr how can I check for heteroskedasticity and fit it if it's exist?
I'm self-studying the ordered logistic regression model, so I didn't covered in any classes. only for linear regressionmodels, such as BP test, chow test. As far I can find these methods are not used for ordered logistic regression.

1There is no assumption of homoskedasticity for logistic regression! See https://stats.stackexchange.com/questions/503092/heteroskedasticity-and-logistic-regression – kjetil b halvorsen Aug 19 '23 at 12:15
