Hi,

the command generate xlag=L.x would have to work. I think this is what you want.

Best,
Marina

Does anyone know how can I create lags when I am using a long format xt
dataset eg:
Id year var1 var2 ......
12 1
12 2
12 3
12 4
13 1
13 2
13 3
13 4
If I use the command generate xlag= x[_n-1] then this will only create one
missing value at the first observation for the individual with the personal
identification mumber 12 and none for the rest- hence -this mixes up
different individuals' observations.
Can anyone help?
George
