多元有序logistic 回归 平行线检验结果问题如下。请问各位，这个结果是检验通过了吗？如果没有通过，怎么改进呢？谢谢您的帮助！
Test of Parallel Linesa                               
Model        -2 Log Likelihood        Chi-Square        df        Sig.
Null Hypothesis        83.674                       
General        68.477b        15.196c        14        .365
The null hypothesis states that the location parameters (slope coefficients) are the same across response categories.                               
a Link function: Logit.                               
b The log-likelihood value cannot be further increased after maximum number of step-halving.                               
c The Chi-Square statistic is computed based on the log-likelihood value of the last iteration of the general model. Validity of the test is uncertain.
