邊距預測結果誤差r（198）

Question

我需要估計xtoprobit估計後的輸出。如果需要的話

但我有r(198)當我運行，

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

運行後，

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

完整的語法：

請研究https://stackoverflow.com/help/mcve對好建議這裏的問題。您的示例不可重複，因爲我們無法訪問您的數據。另外，完整的代碼包含了許多幾乎可以肯定不相關的細節，並使用不明原因的用戶編寫的程序（outreg2）。

r(198)表示語法錯誤，但沒有這樣的錯誤對我來說是顯而易見的。相反，這種運行沒有錯誤在Stata 14.1：

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

因此，建議：

1. 你能在你的Stata運行，沒有錯誤？如果不是，會發生什麼？你使用的是哪個版本的Stata？

2. 檢查代碼是否顯示爲剛好是鍵入的內容。
