STATA 2.1 offers state-of-the-art data management features and statistical procedures capable of handling very large data sets. Its graphics capabilities are excellent as well. Although the package performs a respectable array of econometrics procedures quickly and easily, its menu of available techniques is relatively weak compared to existing econometrics packages. However, since STATA plans a new release to be aimed at the econometrics market, this shortcoming could be mitigated substantially in future versions. Copyright 1991 by John Wiley & Sons, Ltd.
