I published a practical comparison of Python packages for A/B test analysis: tea-tasting, Pingouin, statsmodels, and SciPy.
Instead of choosing a single "best" tool, I break down where each package fits and how much manual work is needed for production-style experiment reporting.
Includes code examples and a feature matrix across power analysis, ratio metrics, relative effect CIs, CUPED, multiple testing correction, and working aggregated statistics for efficiency.
