GNU PSPP vs LatentGOLD

GNU PSPP is free desktop software for statistical analysis of sampled data and a free replacement for SPSS. It provides graphical and command-line interfaces, scripting support, statistical tests, and regression models. Analyses include descriptive statistics, t-tests, ANOVA, linear and logistic regression, cluster analysis, reliability and factor analysis, and non-parametric tests. Data can come from PSPP system or portable files, Gnumeric, ODS, PostgreSQL, and TXT or other delimited text. Results can be written as text, PostScript, PDF, OpenDocument, or HTML. PSPP syntax and data files are compatible with SPSS, with a stated aim of producing similar results. The project lists interoperability with Gnumeric, LibreOffice, OpenOffice.org, and other free software. It supports Linux, macOS, and Windows as desktop platforms. The GNU GPL version 3 or later governs the software. Its listed plan is free, with no license fees or artificial limits on cases or variables.

LatentGOLD is Windows desktop software for latent class and profile analysis, finite mixture modeling, choice modeling, segmentation, clustering and advanced latent-variable work. Its Basic version includes Cluster, DFactor, Regression and Step3 point-and-click modules. Advanced/Syntax adds complex sampling, multilevel latent class models, continuous latent variables, a point-and-click Markov module and the LG-equations syntax language. Choice options cover first-choice, ranking, best-worst, rating and allocation data. The software includes statistical tests, regression models and scripting, and imports ASCII text and SPSS system files. LatentGOLD 6.1 is listed as compatible with Windows 10 and 11; the maker supports installation only on Windows machines. There is no stated record-count limit, although runtime depends on data, machine speed and requested output. The maker identifies researchers, universities, market researchers, consultants and data analysts as users. Eligible university-affiliated students, researchers and educators can request a free academic single-user license for academic or non-commercial research. Pricing includes a 14-day trial and paid plans; listed standard single-user pricing for Basic + Advanced/Syntax is €795 a year.
