Hi all,
I have a problem using the xsmle command for spatial panel estimations. I'm trying to run:
But get the error message:
The error code translates into " numerical overflow".
So here are my questions:
1. Why is this error occuring? My panel contains 5226 obs, so is hardly to large for STATA 13 MP to handle. I also tried different models, weight matrices and var-lists (down to only one independent var) and time-frames (down to 2 years) and the error persists.
2. I've read that with other ML-estimations, it might be possible to set initial values manually, yet I'm not quite clear on how to do that for xsmle. Is that even possible? And exactly what values would have to be set?
I would be grateful for any help or advice you guys could give me.
Best regards,
Tim Umbach
