hi, when I run the Hausman test I get the following message"V_b-V_B is not positive definite", then if I run the test the other way around Like "hausman random fixed" then I get a negative Chi-Square model fitted on these data fails to meet the asymptotic assumptions of the Hausman test; see suest for a generalized test. ? kind regards Ozgur * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
