Hi
Using runmlwin command i have got an error message from MLwiN package implying memory not enough.
The following message also appeared with stata outputs; "Warning: variance matrix is nonsymmetric or highly singular"
How can i increase the memory?
Regards

Could you please post an example of the syntax that you are using that causes this error, as well as a description of your data characteristics? Could you also include the exact error message that you are getting?
