Tables for epidemiologists 
- 2 × 2 and 2 × 2 stratified tables for longitudinal, cohort study, case–control, and matched case–control data
- Odds ratio, incidence ratio, risk ratio, risk difference, and attributable fraction
- Confidence intervals for the above
- Chi-squared, Fisher’s exact, and Mantel–Haenszel tests
- Tests for homogeneity
- Choice of weights for stratified tables: Mantel–Haenszel, standardized, or user specified
- Exact McNemar test for matched case–control data
- Tabulated odds and odds ratios
- Score test for linear trend
Power and sample size
- Stratified 2×2 tables (Cochran–Mantel–Haenszel test)
- 1:M matched case–control studies
- Trend in J×2 tables (Cochran–Armitage test)
Standardization of rates
- Direct standardization
- Indirect standardization
Generalized linear models for the binomial family
- Individual-level or grouped data
- Odds ratios, risk ratios, health ratios, and risk differences
- Bayesian estimation
Additive models of risk New
- relative excess risk due to interaction, excess relative risks,
attributable proportion, and synergy index
- confidence intervals for the above
- models for binary and count outcomes, and survival–time data
Table symmetry and marginal homogeneity tests
- n x n tables where there is one-to-one matching of cases and controls
- Asymptotic symmetry and marginal homogeneity tests
- Exact symmetry tests
- Transmission disequilibrium test (TDT)
Kappa measure of interrater agreement
- Two unique raters
- Weights for weighting disagreements
- Nonunique raters, variables record ratings for each rater
- Nonunique raters, variables record frequency of ratings
Two-way table of frequencies
Brier score decomposition
