Hi,

I am trying to estimate the eventdd technique on panel data using the code created by @Damian Clarke and @Kathya Tapia Schythe.
I am using Stata16 MP with the command:

eventdd ksi_acc trend_la1-trend_la380 ib1.Accident_Month i.weekday $i_ph max_temp min_temp prcp_amt ///
i.LA_code_2009 if LA_code_2009<=10, timevar(trend_mar) method(fe, vce(robust)) leads(2) lags(2) inrange

Unfortunately, I get the following error message:
invalid numlist has too many elements
r(123);

I'm just wondering if the problem is that I have too many fixed effects? I have cut them back to less than 10.
Any help greatly appreciated.

Thank you.
