pnas-statistics

separate

Use to enforce PNAS's statistics and reproducibility reporting — n and replication, test choice and assumptions, effect sizes with uncertainty, multiple-comparison control, randomization/blinding, sample-size justification, pre-registration where relevant, and reproducible code.

When to use

• enforce PNAS statistics reporting
• check reproducibility reporting
• verify effect sizes and uncertainty
• validate multiple-comparison control
• assess randomization and blinding
• justify sample size
• check pre-registration
• review reproducible code

When not to use

• report P without effect size and n
• count technical replicates as independent observations
• infer no effect from non-significant underpowered tests
• present post-hoc findings as pre-specified
