Dear Statalisters, I have problems with stata command gllamm: it says that the likelihood cannot be computed because missing values were encountered during the computation. I don't understand what it means (my data do not have missing values). I have, hopefully correctly, reshaped the data in this way individual alternative choice 1 1 0 1 2 0 1 3 1 1 4 0 etc...for each individual. The command I type is: gllamm alternative age1 age2 age3 age4 un_rate_1 un_rate_2 un_rate_3 un_rate4, i(individual) link(mlogit) expanded(individual choice o) where age1, age2, age3, age4 are age dummies (each for one age category) and un_rate_1, un_rate_2, un_rate_3, un_rate_4 are regional unemployment rates (indeed the alternatives are regions. Honestly, I haven't understood properly what to specify in option i(), however I always get the same error message. Please, can anyone give me a hand? Thanks a lot, Stella -- Stella Capuano c/o Collegio Carlo Alberto Via Real Collegio, 30 10024 Moncalieri (TO) * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
