请教各位


在进行logit回归后，得到Prob>Chi2=0.1172，Log likelihood=-77.19


是否说明这个模型整体不显著，回归没有意义了？

there is problem with the model.  The chi2 is for comparing to the model without any independent variables.

谢谢

是否Prob>Chi2的值小于0.1才能说明模型有意义？

Most use .05.  How large is the data? Is there any significant explanatory variable in the model?

Yes,  but there is only one significant variable.
I don't think the model is good either..
Anyway, is the Log likelihood useful when judge the model? The smaller the better?

likelihood is good to some degree to judge the model if not over specified.  The bigger is better if comparing nested models.  Maybe you can drop some non-significant variables, if your theory permits, and see.

亲，prob＞chi=0.0000是什么意思。

恭喜呗！

恭喜呗！

prob＞chi的值大于0.1的话，即使自变量的系数显著 也不行呗？模型有问题呗？

一般不需要汇报这个。汇报了自变量的显著性以及伪R方。
