Hi, I have noticed the same issue recently. I am not sure if I am using an outdated version, but I would like to see this addressed. After extensive testing, it looks like Mord LogitsticAT agrees with MatLab's mnrfit (link here)––at least up to some floating point accuracy. I would be interested in working on a solution or at least a better understanding of the differences between mord, MatLab, and statsmodels.
Hi There! I am enjoying using your package to analyse ordinal data. However, when I compared the results of
mord.LogisticAT(alpha = 0)
againstfrom statsmodels.miscmodels.ordinal_model import OrderedModel
I obtained different coefficients. Should not they be the same? (As long as I am not using any regularization technique?).Here is a reproducible example:
MORD:
which differ a lot from OrderedModel (coefficient of
pared
is1.0476
in stasmodel and-0.02192845
in mord).Also, could I exponentiate the
model_mort.coef_
and interpret it as the traditionalOdds_Ratio
?Thanks in advance!!
