I am trying to estimate a two-class latent class modeling using lclogit from ssc and its post-estimation command lclogitml (which uses gllamm from ssc) on Stata 14.2.
The model converges when no weights are used, but when I try to use the surveyweights, e.g.
where my survey weight variable name is "pweight2", I receive the following error messages:
The model converges when no weights are used, but when I try to use the surveyweights, e.g.
Code:
lclogit choice $attributes, group(choiceid) lclogitml,iterate(80) pweight(pweight)
