您好，我用的这个命令，但是显示numerical derivatives are approximate
nearby values are missing
numerical derivatives are approximate
nearby values are missing
numerical derivatives are approximate

cannot compute an improvement -- discontinuous region encountered
r(430);
请问这种情况该如何处理？

初步鉴定，数据质量不行。

因为robust是早些年的命令，现在的稳健性用vce(r)，应该就没问题了

明白了，谢谢啦~

两阶段的ivprobit怎么报告稳健标准误。默认的MLE估计是可以报告稳健标准误的。但是help里面没有说两阶段的ivprobit怎么报告
