I have imputed 10 complete datasets using mi. I run mi estimate: logistic pair male time_m bmi on a model. I run a second model using mi estimate: logistic pair male time_m bmi compete efficacy. I want to test if the second model does better than the first. Since there is no log likelihood reported I don't know how to calculate a likelihood ratio chi-square test.How can I compare these models if the log likelihood was not available with the mi estimate command prefix. I could use the lrtest or calculate it by hand using listwise/casewise deletion.
Can't you just use -mi test-, e.g. mi test compete efficacy ------------------------------------------- Richard Williams, Notre Dame Dept of Sociology OFFICE: (574)631-6668, (574)631-6463 HOME: (574)289-5227 EMAIL: Richard.A.Williams.5@ND.Edu WWW: http://www.nd.edu/~rwilliam * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
