Stata 3.1 is a program for data management, graphics, and statistical
analysis. Since Version 2.1 was reviewed by Pederson (1991), Stata has
added several platforms, third-party products, supporting services, a
nd many features of interest to econometricians. The result is that St
rata 3.1 integrates fast and reliable manipulation of data with high-p
owered statistical analysis. For users who do no more than run regress
ions, the new features do not detract from the feel of ease and contro
l Stata gives the researcher working with any data set, large or small
. A unique system to disseminate user-written programs lets Stata grow
continuously without becoming unwieldly, ensuring that Stata will bec
ome a standard package in several branches of applied statistics. This
review summarizes the hardware requirements of Stata, demonstrates a
short but typical Stats session, and discusses some of the unique elem
ents of Stata.
