I am returning to stata after a hatus of a couple of years. I had two quick
questions:
Suppose I am using a stream of time seies data for a single varible (Data,
Variable1):
(1) suppose i wanted to generate a new varible that equale variable1 - the
mean of varible1. how do i do this (without having to create a whole column
with only the mean of variable1 in it)?
(2) is there an easy wasy to test for seasonality? in sas we have the proc
x12 command? what's a quickand eqasy way to test for seasonality in data?
