Re: version 2.25
It sounds like you may have set a worksheet size that is larger than MLwiN is able to allocate. I would suggest that you initially try the steps outlined in http://www.bris.ac.uk/cmm/software/supp ... ml#default to see whether that fixes the problem.

Re: Comparing the DIC
As long as the chains have converged to a stable distribution I believe that the DIC should be comparable. You can find more information on how the DIC is calculated in section 2.2 of the MCMC manual.

Re: sample weights in logistic regression - error message
I am not sure what is causing this specific error, however if you can provide an example worksheet that exhibits that behaviour I will look into it. Please note that we don't recommend using (R)IGLS for logistic regression for the reasons given in http://www.bristol.ac.uk/cmm/software/support/suppor...

Re: unable to allocate 888379 k. worksheet size unchange
900,000Kcells works out as about 3.4Gb which it is very unlikely that MLwiN can allocate in one contiguous block. It is possible that the calculation runmlwin is doing to work out the space needed is wrong, in which case you can try using the mlwinsettings(size()) option with lower values. The highe...

Re: Sampling Weights
Multiple membership with sampling weights is not possible with MCMC in MLwiN. You can set up multiple membership models with (R)IGLS using special commands (see chapter 19 in the MLwiN manual: http://www.bristol.ac.uk/cmm/software/mlwin/download/mlwin-userman-09.pdf ). If you set it up this way then...

Re: Comparing logistic multilevel models
If you're using (R)IGLS you can use a Wald test, as described in the MLwiN manual http://www.bristol.ac.uk/cmm/software/m ... man-09.pdf. For MCMC estimation you can compare the DIC statistics.

Re: multiple membership models
There will also be a module on multiple membership models added to our online course (http://www.cmm.bris.ac.uk/lemma/) in the not too distant future.

Re: RealcomImputeLoad error with import of impvals file
You could either put the list of variables into a local macro and loop through that instead of generating possible variable names, e.g. unab varnames: * or it might be worth comparing your version with the current one available when running: net from http://missingdata.lshtm.ac.uk/stata I just had a...

Re: RealcomImputeLoad error with import of impvals file
I don't know how Stata decides whether there are column names in the text file, but my guess would be that it bases it on whether there is a value in the first row for at least the number of subsequent columns. If you had created 10 imputed data sets then this would correspond with the value of 10 t...

Re: Index exceeds matrix dimensions query
Could you check whether you still get the same problem with the most recent update of Realcom-Impute? There have been some recent bug fixes in the routine that this error message is referring to. As far as the maximum memory it can use goes, Realcom-Impute is currently compiled as a 32 bit windows e...
