Richard. You can create a skewed logit model by fitting a logit model
with a lognormal or triangular constant term. The other coefficients
can be fixed or normally distributed. I would advise, though, don't
specify the RPs to be correlated. That would include the constant term
which would make a mess of things. Note, the distribution of the
random part of your logit model is assumed to be of the sum of a
logistic and a lognormal, which is not a burr distribution, but it is
asymmetric.
