SigmaStat review
A guided desktop statistics package with broad tests, regression, and legacy-data imports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SigmaStat is desktop statistical analysis software from Grafiti LLC for scientists, engineers, researchers, educators, and students. Its toolkit covers descriptive statistics, group and proportion comparisons, categorical data, correlation, regression, principal components analysis, and survival analysis. An advisor wizard helps users select statistical tests, while graphing and customizable reports support interpretation and presentation. The published product information identifies Windows and macOS platforms, with a focus that suits users who want guided procedures rather than a narrowly specialized statistics tool.
Data and ecosystem fit are practical strengths. SigmaStat imports Excel, SPSS, Minitab, SYSTAT, SAS, ASCII/CSV, Access, and ODBC-compliant database data, allowing existing datasets to enter a desktop workflow. Analysis depth includes linear, multiple linear, polynomial, stepwise, subset, logistic, and Deming regression, plus Pearson and Spearman correlation, Kaplan–Meier and Cox regression, and principal components analysis. Its Transform language adds user-defined procedures and equations for analysts who need more control than preset menus provide.
The vendor store lists SigmaStat v1.0 New Product with single-user and upgrade license options, and a 30-day trial is available. Support channels include email and phone. The current listing and the vendor’s SigmaStat 4 documentation describe related product versions, so buyers should match the documented capabilities to the version they intend to purchase. SigmaStat fits solo researchers through enterprise teams that accept desktop deployment and paid licensing; organizations seeking browser access, a free plan, or a fully cloud-native collaboration model should consider another category option.
