Hi everyone, I´m using these regressions models: Ri = const. + B1. Rm + B2.Rw + B3.Xt Rm = const, + B1.Rw + B2.Xt In the first model (Ri) i have no problem to decide the best method to use but in the second model i run random effects don´t appear the p-value of hausman test, only appear the p-value of breusch-pagan. I have checked database and i didn´t found any error. I attached some prints with the models. [image: Modelo 1 Teste Haussman e Breusch Pagan.PNG] [image: Modelo 3 Teste Haussman e Breusch Pagan.PNG] Please can anyone help me. Thanks
