Re: Macro models not converging properly

We have done some investigation of this behaviour and it appears that if you use robust standard errors, set the estimation method to RIGLS and run the model with the Start button then you will get slightly incorrect results. This should be fixed in the next release of MLwiN.

The best documentation that I know of for using weights in MLwiN is the following:

Re: discrete time multilevel event history model

Assuming that you restarted Stata after the update I'm not sure what would be causing this. strtoreal ( http://www.stata.com/help.cgi?mf_strtoreal ) is function that should be part of Stata. You should be able to check whether there is anything else to update with the command update query If you sti...

Re: discrete time multilevel event history model

It sounds as if you may not have Stata fully up to date. According to http://www.stata.com/help.cgi?whatsnew11 the putmata command was added to Stata 11 in the 11feb2010 update. Ideally you would update Stata with the following command: update all If for some reason you are unable to do this then yo...

Re: A question about error:“Macro file not found(OBEY)”

Could you please try running the command again, but this time with the option viewfullmacro added to the end?, i.e. runmlwin normexam cons standlrt, level2(school: cons) level1(student: cons) nopause viewfullmacro This should pop up a window containing the MLwiN commands to fit the model. Could you ...

Re: MLwiN very slow to load data from runmlwin [SOLVED]

To answer your other question, runmlwin should support factor variables in the fixed part but this hasn't been widely tested.

Re: Problem with weights in the latest version of runmlwin

You can turn off this error message by searching for the following text in runmlwin.ado: if `numrp`l'vars' == 0 { if "`diagonal'"~="" || "`elements'"~="" || "`reset'"~="" || "`residuals'"~="" || "`weightvar'"~=...

Re: Modelling proportions

If you can send me an example worksheet, along with instructions on how to replicate the problem I will investigate what is causing this error.

Re: offset for negative binomial models

To answer the question about the inconsistency between the help file and the runmlwin error message, it is the error message that is wrong as MLwiN does allow offsets in negative binomial models. We will fix this message in the next release, but if you are happy editing runmlwin.ado the fix is to ch...

Re: Modelling proportions

As part of fitting discrete outcome models MLwiN uses and names a number of columns. You can see an example of this on the line referred to in the error message that you describe: name c1180 'H' C1181 'F~(H)' C1182 'H*' C1183 'P' c1184 'MASK' c1189 'Y-VAR' If when it gets to this point you already h...
