Before revision: The types of calculations currently performed by OpenEpi include: Various confidence intervals for proportions, rates, standardized mortality ratio, mean, median, percentiles 2x2 crude and stratified tables for count and rate data Matched case-control analysis Test for trend with count data Independent t-test and one-way ANOVA Diagnostic and screening test analyses with receiver operating characteristic (ROC) curves Sample size for proportions, cross-sectional surveys, unmatched case-control, cohort, randomized controlled trials, and comparison of two means Power calculations for proportions (unmatched case-control, cross-sectional, cohort, randomized controlled trials) and for the comparison of two means Random number generator For epidemiologists and other health researchers, OpenEpi performs a number of calculations based on tables not found in most epidemiologic and statistical packages.
