# st: Preliminary results - Matching

 From CARLOS MAGNO SANTOS CLEMENTE <[email protected]> To [email protected] Subject st: Preliminary results - Matching Date Tue, 5 Jun 2012 15:07:49 -0300

```Dear, I would like to help to interpret the results below. And some
explanation about the "Coef. Std Err. Z P> | z | [95% Conf.
Interval]." And if possible the opinion about the consistency of the
results below. Still I'll take the test the robustness of the results

Logistic regression                               Number of obs   =       5183
LR chi2(20)     =    4223.29
Prob > chi2     =     0.0000
Log likelihood = -945.20896                       Pseudo R2       =     0.6908
