Yes yes yes!!! Thank you so very much! Everything is working - even the 3-level multivariate model!

Great to hear that the code for the testdata works for you.
I upgraded my MLwiN version to v2.30 (from v2.28) and installed the R2MLwiN package and library in R before running the code, so I expect that to be the latest version.
Just to try to reproduce your results I continued working on the ...

When I add the debugmode=TRUE and enter MLwiN, I can see that the three levels are set up correctly. However, only the "Fixed Parameter" box is ticked (and none of the three levels, "POSTNR_TXT, chrnr, obsid"). When I tick these levels manually, the model can run in MLwiN.

I tried to set up a ...

Thank you, I was not aware of that. I sorted the data now (postnr_txt-id-obsid), but I still get the same error message. I do not know if it makes more sense if I add the whole R output:

Some input variables held data in more precision than MLwiN supports, these have been rounded

error while ...

Yes, they are there in the real dataset. Sorry, I forgot the "cons" (=1 for all observations) and ID is at the second page in the attachment.

Hi everyone,
I try to run R2MLwin (setting up a 3-level hierarchical multivariate normal model), but keep getting an error message, which I cannot figure out. A testset of the data is attached.
My R coding follows the MLwiN MCMC Manual Ch 18 and looks like this:

install.packages("foreign")
install ...
