Add NuriStat — free open-source SPSS alternative (Python/PySide6)

[baramgay]

What is NuriStat?

NuriStat is a free, MIT-licensed desktop statistics application built with Python and PySide6. It targets academic and clinical researchers who need the familiar menu-driven SPSS workflow without the $99–$1,200/seat/year cost.

Why it belongs here

• Desktop GUI statistics tool for data scientists and researchers (similar to PandasGUI already in the list, but focused on statistical analysis)
• Python ecosystem: PySide6, pandas, scipy, statsmodels, lifelines, pyreadstat
• 27+ analysis modules: t-tests, ANOVA (one-way, two-way, repeated-measures, ANCOVA, MANOVA), linear/logistic/multinomial regression, factor analysis (PCA), K-means, Kaplan-Meier, Cox regression, ROC, Cohen's Kappa, ICC, Bland-Altman, Cronbach α
• SPSS .sav compatibility: import/export with full metadata (variable labels, value labels, missing codes) via pyreadstat
• Effect sizes included automatically (Cohen's d, η², OR, HR)
• MIT licensed, actively developed

Placement

Added after the Pandas GUI entry in the tools table — it fits naturally as another GUI-based data analysis desktop tool.
