Hi, I'm still new to GRETL, so please pardon a simple question. I want my students to generate a simple random walk of, say 1000 values, so that they can compare (graph) this against changes in the DOW. How is a random walk generated in GRETL? More fundamentally, how do I lag a series and use it on the right-hand-side? I tried
genr rw = lags(dow, 1) + randgen(N, 0, 1) but this didn't work. Thanks, Walt Paczkowski -- ________________________ Walter R.
