Power Eval

PowerEval is a Shiny app that enables interactive computation of the sample size required or evaluation of the power for a test intended to determine if there is an association between the probability of an outcome of interest and the level of the exposure factor. In other words, Power and Sample Size for Two-Sample Proportions Test. The computations are based on the Pearson’s chi-squared test for two independent binomial populations and are performed for a two-sided hypothesis test.
