+free replacement for the proprietary program SPSS, and appears very similar
+to it.
+
+PSPP can perform descriptive statistics, T-tests, anova, linear and logistic
+regression, cluster analysis, factor analysis, non-parametric tests and
+more.  Its backend is designed to perform its analyses as fast as possible,
+regardless of the size of the input data.  You can use PSPP with its
+graphical interface or the more traditional syntax commands.")
