Hi everyone, I am doing an event study analysis and when I use the estudy command, I get this error:


"The event date must be 8 characters long
r(198);"

Do you know what does it means? My date variable is in this format %tdNN/DD/CCYY, so it should be in the correct format.

These are the codes I'm trying to run.

Code:
estudy ri1-ri160, ///
datevar(date) evdate(security_name event_date) /// 
modt(SIM) dateformat(MDY) diagn(BMP) ///
lb1(-3) ub1(2) dec(4)
Thank you very much
