GNU project in alpha state. PSPP is a program for statistical analysis of sampled data. It interprets commands in the SPSS language and produces tabular output in ASCII, HTML, or PostScript format. The name PSPP is not intended as an acronym, but it is easy to invent expansions for it. In previous releases, PSPP was known as Fiasco. This web page corresponds to PSPP version 0.2.0. PSPP development is ongoing. It already supports a large subset of SPSS's transformation language. Its statistical procedure support is limited but growing. A manual is available.
