Greetings, I am estimating a 3-level multinomial model which seems to have no problems with convergence. However, once I replace GDP pc with a set of GDP pc dummies denoting the five quintiles of its distribution (using the first one as a reference category) I get an error message saying illegal op:...

Dear George,

Many thanks for your reply and apologies for bothering you with such a simple question. In fact, I've read both runmlwin help and ch10 of MLwin manual on multinomial modeling, but it looks like this bit has somehow skipped my attention. Thanks once again.

Kind Regards,
Julia

Dear George,

Many thanks for your response and useful information. I am sorry for asking, perhaps, a stupid question. Does runmlwin return the model results to STATA automatically or do I have to use a specific command for this?

Kind Regards,

Dear Chris, I think I've just found an answer to my previous question. Is it becase in MLwiN response categories form level 1 and so individuals (setid) are level 2 and so forth? Many thanks for all your help so far - your advice was extremely useful. I am just wondering is there any way to get sign...

Dear Chris, Thanks for your advice. Yes, I think the size of the dataset was a problem. I've reset the size of the worksheet and the msg 'line too long' no longer appears. I've started running the model just now. One thing that bothers me at this stage is that I got the message "Unexpanded leve...

Dear Chris and George, Thanks for looking into this. It may be a bit complicated as even after compression the file is about 500MB. It has about 700,000 obs. I may delete some variables not currently in use and will deal with missing values so to reduce the size of the file after I finish running th...

Dear George, Thanks a lot for your advice. Below is the macro for my model. ECHO 0 NOTE *********************************************************************** NOTE MLwiN macro created by runmlwin Stata command: 19 Aug 2011, 22:46:12 NOTE See: www.cmm.bristol.ac.uk/runmlwin for help NOTE ***********...

Would appreciate your advice on how to use this 'viewmacro' option. I've tried to insert it after comma in the model before specifying the levels but it didn't work. Please advise.

Dear George and Chris,

Thanks a lot for your advice. I've solved the problem of missing values, but I still get the message 'line too long' after getting all the cases with MVs removed. Please advise on what this may be attributed to and how to solve this.

Kind Regards,
Julia

Greetings, I am quite new to MLwiN and when I attempted to use it from within STATA I encountered a few problems. (1) My dependent variable so are some of my explanatory variables contain missing values. I am using mlogit within multilevel setting and I don't want to use imputation technique to solv...
