[Gretl-users] Gretl error/crash

Hi, I'm currently attempting a multinomial logit model on a large sample of panel data. I'm having a problem where I need to be able to create dummies for each individual in the sample to control for the individual fixed effects. In order to do so while using the logit model, I need to dummify the person ID (PID) in the sample. I've opened the gretl console and I enter the following commands: discrete PID <----transform the variable, 19,421 values, to be discrete dummify PID <----create dummies for each individual to control for fixed effects The last command causes gretl to crash, giving a libcairo_32.dll error. This happens on whichever computer I am using. Occasionally, if I use the menus instead of the console, it will give an 'out of memory' error. My PC is definitely sufficiently powerful. Does anyone have any ideas as to how I can get around this issue? Thanks, Simon
