eventstudy2 error: variable __000016 contains all missing values

[Howk Crawford]

Hello,

I'm using eventstudy2 for regression. Until this morning, I was able to run all the data completely, but after I changed the car1UB(x)-car10UB(x) value range, I could only generate AR, AAR and CAR data. When generating CAAR data, variable __000016 contains all missing values. I don't know the specific cause of the error, trying to re-import the dta data and run again can't solve it. Can anyone solve this problem?
As my mother tongue is not English, I used translation software, which may affect your reading experience. I apologize for this.

I thought that I found the problem……I dropped a "-" in car6LB()
