Dear Statalisters, I have three variables (a; b; C with 10,000 observations each) in long format. For each value of a I would like to obtain the following one: (a1 * b1) - c1 . . . . (a1*b10,000)-c10,000; Repeat the above reported would-be 10,000 times (i.e., from a1 to a10,000) Create a new variable d in which the mean of each one of the 10,000 iterations are stored and can be displayed. I suppose there's way of doing this with Stata 9.2/SE, but I cannot figure out the proper syntax. Thanks a lot for your kindness and for your time.
