Dear Statalisters,

I am sure some of you have taught statistics/econometrics courses using Stata and recommended that students buy Small Stata.
The advertised limitations for Small Stata do not seem too restrictive: a maximum of 99 variables, 39 right-hand variables, 1000 observations and a matsize of 40.
The course I am teaching is on economic forecasting. I am using the book
"Elements of Forecasting" by F. Diebold and contrary to the examples on the book (which are on Eviews) I decided to use Stata. Unfortunately, I am finding out that the students can not replicate some of the examples on the book because of the restrictions on Small Stata. For example, they are unable to estimate an ARMAX with 12 seasonal variables using 400 observations. From the general description of Small Stata it never crossed my mind that they couldn't do it. This has been a frustrating experience as I am never sure what exactly are the limitations of Small Stata. I definitely would expect it to be able to run most "textbook examples" and I naively assumed that to be true.
Paulo,

We fully intend for Small Stata to be able to run most examples that are encountered in textbooks; an ARMAX model with 12 variables should be within the grasp of Small Stata. If you send me (bpoi@stata.com) a do-file and dataset illustrating some of the examples that do not work with Small Stata, I will search for an alternative so that students can in fact do them. I will also report back to statalist once we arrive at a solution.
