Dear Statalisters

I estimeted a panel model, and itīs used, pooled regression, fixed efect
and randon efect. After this, when the stata run the hausman test, the
result is negative. The message is that the matrix is not positive
definite. In this form, I donīt know if the fixed efect is more efficient
than randon efect. How can I do?

Best regards,

Rodolfo
