"Very exciting things are happening in personal computer software…. The most impressive statistical package we have seen so far is TINY TROLL, a multiple linear regression package from Micro Finance Systems....TINY TROLL performs the kind of statistical calculations that one normally sees only on large computers.... For instance, TINY TROLL routinely will regress up to nine independent variables and one dependent variable. Moreover, it plots them in high resolution graphics on the screen for visual inspection of their correlation...." - Benjamin Rosen, Electronics Letter, October 19, 1979. "The first attempt to perform a regression on the microcomputer predates the IBM PC.... At the end of the 1970s, prior to his better known work on Lotus 1-2-3, Mitch Kapor, then at MIT, created a microcomputer regression program for the Apple II, loosely based on TROLL, which he called TINY TROLL." - Charles G. Renfro, "Econometric Software: The First Fifty Years in Perspective," Journal of Economic and Social Measurement, 29, 2004.
