Dear All
I have read a lot of threads on this issue, but still can not resolve my problem:
I am trying to run FGLS (xtgls) with 49,000 observations, 8 years unbalanced panel with around 7,500 groups, 26 varibles in the model.
After first trying xtgls I get a message saying "matsize too small - should be at least 7369". So, I set matsize to 8000, then I get a message r(909) "op. sys. refuses to provide memory". Could you please help me understand what is causing the problem here, and how to reslve it? I presume it is not related to the number of observations or variables, but rather caused by the way FGLS works.
Resources in use:
- 32 bit Windows 7
- RAM 4g
- Stata/SE 12.1
- Stata "About" shows Available Physical Memory 1,945,452 KB
- max_memory set to .
Memory report is as follows:
