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 a one-to-one matching of cases and controls
• asymptotic symmetry and marginal homogeneity tests
• exact symmetry tests
• transmission disequilibrium test (TDT)

U.S. Food and Drug Administration (FDA) submittals

• read and write data in the format required by the FDA for new drug application (NDA) submittals
• describe the contents of data written in the FDA required format
• Produce an Installation Qualification (IQ) report
  

Receiver Operating Characteristic (ROC) curves

• Fit ROC regression models, with covariates*
  
• calculate area under curve
• calculate partial area under the curve*
• Obtain sensitivity for a given specificity, and vice versa*
  
• Test equality of ROC area against a "gold standard"
• Sidak's adjustment for multiple comparisons
• Easy ROC curve plots for different classifiers and covariate values*
  

Generalized linear models for the binomial family

• individual-level or grouped data
• odds ratios, risk ratios, health ratios, and risk differences

Pharmacokinetics

• pharmacokinetic measures from time-and-concentration subject-level data
• test that measurement is normally distributed
• analysis of data from crossover design experiment
• test of bioequivalence for two treatments

ICD-9-CM diagnostic and procedure codes

• verify variable contains valid codes
• modify codes to display in standard format
• V28, V26, V25, V24, V22, V21, V19, V18, and V16 codes
  
• display description of codes
• display the identity of source
