Hi,
this might be a rather simple questions, but I don't get it to work, so help is appreciated.
I try to generate a variable that is simply the mean value of another up to this point in time, so a kind of rolling-mean. Example:
var_x | var_mean
1| 1/1
4 | 5/2
3 | 8/3
7 | 15/4
2 | 17/5
Regards,
Leon
