多项logit回归不满足“无关方案独立性”的假设,应该采取什么办法解决的,有什么其他模型可以处理这种多值被解释变量吗,还是需要处理数据或者变量。用stata回归的,结果如下。基准组设的1。
. mlogtest, hausman base
Hausman tests of IIA assumption (N=1315)
Ho: Odds(Outcome-J vs Outcome-K) are independent of other alternatives
Omitted | chi2 df P>chi2 evidence
---------+------------------------------------
1 | 6.142 64 1.000 for Ho
2 | -0.776 65 --- ---
3 | -3.282 64 --- ---
4 | 3.264 64 1.000 for Ho
5 | -0.514 64 --- ---
----------------------------------------------
Note: If chi2<0, the estimated model does not meet asymptotic assumptions.
