Why not just v1[_n-1] ? Apart from missing values in the time domain, that will do the same thing.In my dataset there is a variable v1, which is a string variable. I try to use l.v1, after i set the time variable (eg, tsset time). I don't know why stata do not permit timeseries operators on string variables, it seems not reasonable for the lag or lead operators, beyond the difference operators i wonder if there is some sort way so that i can use the laged string variable?
