Hello,
I'm estimating an ordered logit model on a probability weighted survey
sample. polr permits case weights with the "weights" option, but I cannot
figure out from existing documentation what it actually does with these
weights. I'm concerned about this because I get somewhat different
results using Stata's ologit command with the pweights option and very
different results using proc logistic in SAS with its weight option. So
my basic question is whether or not it is appropriate to use the weight
option for polr with my data.
Best,
Greg
