做了一个logistic的回归,看不太懂回归结果.大家帮忙看一下拉,在线等.

Iteration 0:   log likelihood =  -1830.509
Iteration 1:   log likelihood = -1786.6002
Iteration 2:   log likelihood = -1786.0478
Iteration 3:   log likelihood = -1786.0458
Iteration 4:   log likelihood = -1786.0455
Iteration 5:   log likelihood = -1786.0431
Iteration 6:   log likelihood =          .

Multinomial logistic regression                   Number of obs   =       1911
                                                                    LR chi2(12)     =          .
Log likelihood =          .                               Prob > chi2     =          .
