StatCalc
Introduction
StatCalc is an epidemiologic calculator that produces statistics from summary data. Three types of calculations are offered:
- Statistics from 2-by-2 to 2-by-9 tables similar to those produced in Analysis. Both single and stratified 2-by-2 tables can be analyzed to produce odds ratios and risk ratios (relative risks) with confidence limits, several types of chi square tests, Fisher exact tests, Mantel-Haenszel summary odds ratios and chi squares, and associated p-values.
- Sample size and power calculations include Population Survey, Cohort or Cross-Sectional, and Unmatched Case-Control Study.
- Chi-square for trend by the Mantel extension of the Mantel-Haenszel summary odds ratio and chi square. This tests for the presence of a trend in dose response or other case control studies where a series of increasing or decreasing exposures is being studied.
