边距预测结果误差r（198）

Question

我需要估计xtoprobit估计后的输出。如果需要的话

但我有r(198)当我运行，

margins, at(HealthStatus=(1(1)4)) predict(outcome(1)) 

运行后，

xtoprobit Ages HealthStatus ChildSex Family1 Family2 FatherPresent MotherPresent FatherEducation MotherEducation Location Income, iterate(0) 

完整的语法：

请研究https://stackoverflow.com/help/mcve对好建议这里的问题。您的示例不可重复，因为我们无法访问您的数据。另外，完整的代码包含了许多几乎可以肯定不相关的细节，并使用不明原因的用户编写的程序（outreg2）。

r(198)表示语法错误，但没有这样的错误对我来说是显而易见的。相反，这种运行没有错误在Stata 14.1：

webuse tvsfpors, clear 
xtset school 
xtoprobit thk prethk 
margins, at(prethk = (0(1)6)) predict(outcome(1)) 

因此，建议：

1. 你能在你的Stata运行，没有错误？如果不是，会发生什么？你使用的是哪个版本的Stata？

2. 检查代码是否显示为刚好是键入的内容。
