st: re: averaging within a variable

[Kit Baum <baum@bc.edu>]

And here is a pure Mata solution to that problem:

clear
set obs 100
g Var1=_n

mata:
	v1=st_data(.,"Var1",0)
	v3 = colshape(v1',2) * J(2,1,0.5)
	res=st_addvar("float","Var2")
	st_store((1,rows(v3)),res,v3)
	end
list

This version will work for whatever number of observations are in Var1, 
as long as it is even.
