Correlated Random Effects - Hausman Test   
Pool: Untitled   
Test cross-section random effects   
   
Test Summary  Chi-Sq. Statistic Chi-Sq. d.f. Prob.
   
Cross-section random  0 2 1
   
* Cross-section test variance is invalid. Hausman statistic set to zero.   
为何hausman检验总是概率为1，总是接受原假设呢，* Cross-section test variance is invalid. Hausman statistic set to zero.
而且有这样一段话！，是模型设置错误吗，不会的啊！真诚求教~
希望能够帮帮忙~真心谢谢了
