Re: constraint in MVML model

You may just be missing the brackets for the option. For example syntax using constraints see chapter 18 of the MLwiN User's guide replication script: http://www.bris.ac.uk/cmm/media/runmlwi ... d_Data.log.

Re: Multilevel negative binomial model selection using R2MlwiN

If you're running the model via MCMC then you could compare the DIC statistics, otherwise I think that your only option would be a Wald test.

Re: New version of MLWin Not Recognizing Missing Values

Do you happen to know which version of MLwiN the problematic worksheets were saved with? MLwiN uses a very large negative value (-9.999e29) to signify missing data. It could be that somehow your previously missing values have deviated from this slightly and are no longer recognised as such. If this ...

Re: Pratical help - open worksheet

Can you confirm that you are actually saving an MLwiN worksheet (.ws or .wsz) and not in a data format for another package? Other packages require rectangular data, so when saving files for use in these MLwiN has to fill in the gaps with missing values. This becomes a particular problem when saving ...

Re: Level Identifiers

If you were to follow the same model structure as in chapter 13 of the MLwiN User's Guide ( http://bristol.ac.uk/cmm/software/mlwin/download/manuals.html ) then you would put occ (i.e. 1,2,3,4,5,6,...) as the level-1 identifier and person_id (i.e. 1,1,1,2,2,2,...) at level-2, before switching the mo...

Re: Adding and specifying terms

If you were able to send an example worksheet demonstrating the problem and/or screenshots of the model to myself and Bill (seehttps://www.bristol.ac.uk/cmm/team/ for contact details) we should be able to check whether there are any obvious problems with the model/data.

Re: Level Identifiers

Sorry that this has taken a while for me to be able to look into. Can you confirm that you specified a denominator for your response (by clicking on the red nj in the equation), as I was able to get the software give the following error if I omitted this and then attempted to run the model: --------...

Re: Level Identifiers

If it is at all possible to provide me with an example worksheet, along with replication instructions for the crash I can look into what is causing this to happen.

Re: Level Identifiers

MLwiN shouldn't crash when you make changed to the model, even if the specification is wrong. Can you confirm that you are using the most recent version (3.05), as I am not aware of any current bugs which would cause this?

Re: Level Identifiers

I should add that if you're already familiar with runmlwin you can use this to set up the model. To do this just make sure that you haven't specified the nopause option, then once it has started up MLwiN and set up the model you can just click the Abort Macro button and carry on from there.
