Re: Variable not allowed
It looks as if insheet is reading all the variable names into one variable instead of creating one for each. This means that rename is attempting to rename the variable v1 to the whole list of names in your data. You should be able to confirm this with the command: insheet using impvals.txt, clear n...

Re: Large SEs after imputation
Clicking: imputation -> start analysis is the correct way to perform the analysis on your set of imputed data. It doesn't turn green because the results from several model fits have been combined and therefore don't technically match the last remembered iteration. If you press "start" then...

Re: Residuals - matching
For cross-classified models the residual number should correspond to the sorted ID numbers for that classification, i.e. if your classification is in column c1 and you wanted a short version in c2 to match the residual ordering then the command: UNIQ c1 c2 should give you a short ID column in the co...

Re: imputed dataset (long form) & realcomImpute for Linux
Unfortunately this currently isn't available and we don't have access to a Linux version of Matlab to build it. The Realcom-impute application isn't directly called from Stata it just outputs files that the -realcomImpute- Stata command can use. This means that you can impute the data using a Window...

Re: imputed dataset (long form) & realcomImpute for Linux
1) There isn't an option to save as one output dataset, however as you are using Stata you should be able to use Stata's http://www.stata.com/help.cgi?mi commands to convert the data to the format that you want. To do this you would use: mi import flongsep ... to load all the data files and then: mi...

Re: Variance- Covariance matrix
Manually setting the starting values is covered in chapter 5 of the MCMC manual (see http://www.bris.ac.uk/cmm/software/mlwi ... ection.5.5).

Re: Variance- Covariance matrix
If you're getting all zeros for the level 2 covariance matrix then it's worth checking the hierarchy viewer to make sure that it matches what you expect. If not then your data may not be sorted by the model hierarchy. Assuming that it does look as expected you can choose alternative starting values ...

Re: logistic multilevel error
That's a bit of a mystery then. I would suggest that you update to the most recent version of MLwiN ( http://www.bris.ac.uk/cmm/software/mlwin/download/upgrades.html ) in case this was caused by something that has been fixed since version 2.21. If the error message is highlighting the correct locati...

Re: logistic multilevel error
Have you checked whether the version of MLwiN is the same on both machines? If it isn't then what are the version numbers of the one that works and the one that doesn't?

Re: logistic multilevel error
Without seeing your model/data I can't give a definite reason for this error message. What linearisation method are you using? You will sometimes see messages like this when it is having trouble fitting using second order PQL. If this is the case you can sometimes get the model to converge by first ...
