Can it perform Bayesian alternatives to frequentist tests?

Yes, it leverages PyMC and ArviZ to provide Bayesian versions of t-tests and ANOVA, offering Bayes Factors and posterior probability statements.

Does this skill support non-parametric tests?

Yes, it includes robust alternatives such as Mann-Whitney U, Wilcoxon signed-rank, and Kruskal-Wallis tests for datasets that violate normality assumptions.

What Python libraries are required for this skill?

The skill utilizes industry-standard libraries including Scipy.stats, Statsmodels, Pingouin for general statistics, and PyMC for Bayesian modeling.

Does it check for statistical assumptions automatically?

Yes, it includes systematic verification for normality, homogeneity of variance, outliers, and linearity before running tests to ensure results are valid.

Can I use this for professional APA reporting?

Absolutely. The skill is specifically designed to generate statistical results in standard APA format, including effect sizes and confidence intervals, suitable for research papers.
