Hi all-

I am wondering how I can create the event time variable. For example I want to create something like this:

Time         	Event 	EventTime 
2000m1		No	-2
2000m2   	No	-1
2000m3		Yes	0
2000m4		No	1
2000m5		No	2

Furthermore, what I actually want to create is the following:

Time         ID	Event 	EventTime 
2000m1		No	-2
2000m1		No	-2
2000m2   	No	-1
2000m2		No	-1
2000m3		Yes 	0
2000m3		Yes	0
2000m4		No	1
2000m4		No	1
2000m5		No	2
2000m5		No	2

Could you please help me out?

Best,
JK
