You can override the MLwiN worksheet settings using the mlwin_settings() runmlwin options as described in the help file.

This error indicates that the variable used to store the total size of the matrix (number of columns * number of rows) doesn't have enough capacity to store this size and has wrapped around. The check that triggers the error is to divide this total by the number of rows and check that the number is ...

If you can provide us with information on: 1) The exact error message that you are getting. 2) Details of the model that you are trying to run (possibly including the runmlwin syntax you are using). 3) Details about your data (number of cases, does it contain missing data, etc). then we might be abl...

If MLwiN is now always crashing on startup then it is likely that you have set a default worksheet size that is too large. You can reset the size to its default by using the /reset command line option (see http://www.cmm.bris.ac.uk/forum/viewtopic.php?f=1&t=553).

If you're using version 2.26 you can use the /reset command line option to reset the worksheet settings back to their defaults. This and other command line switches are documented in the manual supplement (http://www.bristol.ac.uk/cmm/software/m ... ection.8.5).

1) SSP Matrix is short for "sum of squares and products matrix". 2) This and other warning messages are covered in http://www.bristol.ac.uk/cmm/software/support/support-faqs/errors.html , although they normally apply to (R)IGLS estimation. It's worth checking that your data has the expecte...

You can find this under the "Help->Contents and index" menu within MLwiN.

I just checked this with Professor Kelvyn Jones and his response is below: The customised predictions is primarily a tool for making predictions with confidence intervals for the fixed part of the model; although as you noted it also provides coverage intervals (also with confidence intervals) for t...
