For authors and reviewers
Verify your statistical analysis before you submit
Upload your dataset and re-run the reported analyses on the real data. We check whether each result reproduces, whether the test was the right one for the design, whether its assumptions hold, and whether corrections and effect sizes were handled properly.

What it checks
Reproduction
We recompute the statistic, p-value, confidence interval and effect size from your data and compare them to what was reported.
Right test choice
We check that the test fits the design and the data type, and recommend the correct one (Welch, non-parametric, logistic, Fisher, Cox, random-effects) when it does not.
Assumptions
Normality, equal variance, multicollinearity, proportional hazards, expected cell counts and more, checked on the real data.
Corrections, effect, power
Multiple-comparison corrections, effect sizes with bootstrap confidence intervals, and a guard against reading a non-significant result as no effect.
Supported analyses
Nineteen families of tests, grounded in the reporting standards SAMPL, CHAMP, STARD, PRISMA, TRIPOD, GRRAS and BARG:
- Group comparisons (t / Welch / Mann-Whitney / Wilcoxon)
- ANOVA and Kruskal-Wallis
- Association (chi-square, Fisher)
- Correlation (Pearson, Spearman)
- Regression (linear, logistic, Poisson, negative binomial)
- Survival (Kaplan-Meier, log-rank, Cox with proportional-hazards check)
- Diagnostic accuracy (sensitivity, specificity, PPV, NPV, ROC and AUC)
- Reliability and agreement (ICC, Cronbach alpha, kappa, Bland-Altman)
- Mixed and repeated-measures models
- Equivalence and non-inferiority (TOST)
- Propensity-score balance
- MANOVA
- Prediction-model validation (discrimination and calibration)
- Discriminant analysis (LDA, QDA)
- Meta-analysis (fixed and random effects, heterogeneity, publication bias, subgroup, meta-regression, trim-and-fill)
- Bayesian t-test (Bayes factor) and MCMC convergence diagnostics
