Check event counts, exposure units, and log-Wald assumptions before comparing two event rates.
Summarize Categorical Diversity
Use Shannon and Simpson summaries to describe category distributions without turning diversity into a clinical quality score.
Audit Binary Prediction Scores
Calculate a binary Brier score from valid aggregate inputs and distinguish overall probability accuracy from calibration.
Report a Paired Mean Difference
Use the standard deviation of within-person differences and a Student t interval for a paired mean estimate.
Choose Calibration Bins Without Hiding Error
Audit bin boundaries, sample sizes, and aggregation before interpreting a probability calibration plot.
Prevent Leakage in Prediction Validation
Keep preprocessing, model selection, and outcome timing inside a reproducible validation design.
Audit Reverse-Keyed Questionnaire Items
Verify scoring direction, category bounds, and missing-value handling before calculating a questionnaire total.
Check the Poisson Mean–Variance Assumption
Separate heterogeneous exposure from residual overdispersion before trusting a simple Poisson rate comparison.
Recover Counts Compatible with Rounded Percentages
Identify integer counts consistent with a reported percentage without claiming that rounding reveals the original data.
