Long and Freese keep the most current versions of their programs on Long's own personal pages. Incidentally, keep in mind that mlogit can also estimate a logistic regression model; ergo you might sometimes want to use mlogit instead of logit so you can take advantage of the mlogtest command. You used the old syntax of Feb 18, 2016 · I estimate a multinomial logit model of school choice on survey data, and try mlogtest to test IIA. Your question will see a much larger audience if you post it in Statalist's General Forum. If you wanted the reference category to be the value 2 of y_mult, you could use this: mlogit y_mult x z, base(2) The problem is that -mlogtest- will not perform the Hausman test. The findit command first searches Stata's official help files and notes that there is an official heckman command and several other related commands (this makes findit a powerful tool for figuring out how to do things in Stata in general, not just for finding user-written programs). mlogit y_mult x z mlogit y_mult x z, rrr If you want to change the reference category, the simplest method is to add the base() argument. estadd mlogtest [varlist] [, mlogtest_options ] applies mlogtest from Long and Freese's SPost package and adds the returned results to e(). Hi Natalia, I haven't personally done a Chow test using an Mlogit model, however I believe the right syntax is: mlogit Y x1 x2 x3 if period==0, base (0) est store model1 mlogit Y x1 x2 x3 if period==1, base (0) est store model2 suest model1 model2 test [ model1_mean=mode2_mean] Look at example 2 of the -suest- help file. Moreno. These packages are available at SSC. We Stata will do the Small-Hsiao test, but it won't run the -mlogtest, iia- and -mlogtest, hausman- because of "invalid syntax". mlogtest, iia **** Hausman tests of IIA assumption Ho: Odds (Outcome-J vs Outcome-K) are independent of other alternatives. sex. I > have 17 independent variables. log close log: d:datastatamlogit. I agree - I get nervous about using multiple-outcome commands like mlogit with In Stata you will rarely encounter this perspective, the only exceptions are when dealing with BICs or when you are using the winbugsfromstata package by J. As postestimation checks I tried to carry out a test for the equality of coefs across categories: mlogtest, c before despalying the output of thus check, STATA (version 12) says: mlogtest, c Problem determining number of categories. 648 6 1. oarc. 6 jsl 2009-10-18 Again, I suggest running a really minimal model where you have only one or two x variables, e. iia no coefficients in common; specify Dear All, I confirm that my current version of mlogtest is and was the one indicated by Nick, precisely: . Each pair of outcomes is labeled (Model 1 and Model 2 respectively.
