Hello everyone,
I am going through the worked examples for random effects models of Appendix D of the markbook. Following the example step by step, things seems to go well until I get the message 'Append this Model's output to database?' When I click 'yes', I get an Info message saying 'Could not import variance-covariance matrix to record'. The model is then added to the the output table but is expectedly way off in terms of deviance with empty or zero estimates.
Has someone encountered a similar behaviour, or am I missing something in the procedure ?
It is the last available version of mark, ran under the wine emulator (v 1.5.31) on a ubuntu raring (64 bits) laptop (other than the above problem, mark works pretty well under wine).
Thanks in advance for your help.
Olivier
