Guided statistical analysis: test choice, assumption checks, effect sizes, power, APA reporting. Pick tests, verify assumptions, or format results for publication. Covers frequentist (t-test, ANOVA, chi-square, regression, correlation, survival, count, reliability) and Bayesian. Use statsmodels or pymc-bayesian-modeling to fit.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Statistical Analysis ## Overview Statistical analysis is the systematic process of selecting appropriate tests, verifying assumptions, quantifying effect magnitudes, and reporting results. This knowhow guides test selection, assumption diagnostics, and APA-style reporting for frequentist and Bayesian analyses in academic research. ## Key Concepts ### Frequentist vs Bayesian Framework | Aspect | Frequentist | Bayesian | |--------|-------------|----------| | Core output | p-value, confidence interval | Posterior distribution, credible interval | | Interpretation | "How likely is this data if H0 is true?" | "How likely is H1 given the data?" | | Null support | Cannot support H0 (only fail to reject) | Can quantify evidence for H0 via Bayes Factor | | Prior info | Not used | Incorporated via prior distributions | | Sample size | Requires adequate power | Works with any sample size | | Best for | Standard analyses, large samples | Small samples, prior info, complex models | ### Statistical vs Practical Significance A statistically significant result (p < .05) may be trivially small in practice. Always report: …

How to install
mdr add jaechang-hits/sciagent-skills/statistical-analysis@sha256:163f44563bbc80b8The line at the top of this page pins the label git:20260428.81ea2d2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
