POWER Software

Description:
This program permits the determination of the power or sample size for epidemiological studies testing an effect of one factor or testing of an interaction effect between two factors. POWER V.3.0 has been upgraded with the following new features:

• Power/sample size for one exposure (binary or categorical with multiple levels);
• Probability distribution for exposures;
• Entry of values for either marginal odds ratios or main effects odds ratios for the specification of the alternative hypothesis;
• Improved handling of log and output files; and minor bug fixes.
