Standardization of rates

  • Direct standardization
  • Indirect standardization

Tables for epidemiologists

  • 2 x 2 and 2 x 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

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)
