Hey all,

I do a bivariate probit regression, and to test heteroscedasticity I used linear regression and got the next results, so what do you think for the procedure first and the second for the results, meanwhile the second test with low chi2.

the work is on stata

Breusch-Pagan / Cook-Weisberg test for heteroskedasticity
Ho: Constant variance
Variables: fitted values of norecordedsub

chi2(1) = 5897.97
Prob > chi2 = 0.0000


Breusch-Pagan / Cook-Weisberg test for heteroskedasticity
Ho: Constant variance
Variables: fitted values of expo

chi2(1) = 6.54
Prob > chi2 = 0.0106

thnx in advanced
