The syntax should still match that in the help file, however it is possible that one of the undocumented options may have changed. Alternatively a bug may have crept in that wasn't picked up in testing. Would it be possible for you to provide an example of the syntax that fails?

It appears that you have hit Stata's limit for the maximum number of characters that can be stored in a macro. As this is affected by the maxvar setting you can increase this (up to a maximum of 32767 characters) with a command like the following: set maxvar 32767 Once you have done this you should ...

A trial version of MLwiN which should be compatible with runmlwin is now available from http://www.bristol.ac.uk/cmm/software/mlwin/download/.

Are you telling runmlwin where to find mlwin.exe via the mlwinpath option, or via the $MLwiN_path global? I think that there is currently a bug where it is always expecting to find it in $MLwiN_path while displaying the results. We will fix this in a later version, but in the mean time the workaroun...

The parameter chains are stored by default in c1090 as a sequence of successive sets, one for each iteration. Within each set the parameters are stored with the fixed parameters first, followed by the random parameters. The order of these should match that in the equations window. You can extract a ...

I believe that some people do use MLwiN in this way, but I have no direct experience in doing this. MLwiN does not use multiple processors, so the best way of taking advantage of this environment would be to run several copies of MLwiN in parallel.

The "cannot allocate smatrix" message will appear if there is not enough worksheet space to store a matrix. You may be able to get around this by increasing the worksheet size, however if the data is corrupted this may not work as it may be trying to allocating an impossibly big matrix. Th...

You can check whether (R)IGLS models have converged by looking in e(converged), although if the macro doesn't finish running this might not be filled in. There is already an MLwiN macro command to ignore errors in macros (ERRO 0) which is sometimes used in simulations. We shall investigate whether t...

I just had Stata update to 11.2 here too, although I still get the same popping under behaviour as before if another application has focus (even another instance of Stata).

This is currently implemented as a sub option of the MCMC option i.e. mcmc(paex(2 3)) to specify parameter expansion at levels 2 and 3. As the MCMC functionality is still being developed the exact syntax may still be subject to change in the future.
