I apologize in advance if this question is silly, but how do I create a mean variable by groups. Take the below table for example, I want to calculate a Var2 such that for the first 3 observations, Var2 is the mean(Var1 of the first 3 obs), and Var2 for the next 7 obs is mean(Var1 from id=4 to id=10). ie, to get from Table 1 to Table 2. Thank you!

Table 1

from table1
