ECR: Compute the empirical coverage rate for Type I errors and Power

Description

Computes the detection rate for determining empirical Type I error and power rates using information from the confidence intervals. Note that using 1 - ECR(CIs, parameter) will provide the empirical detection rate.

Usage

ECR(CIs, parameter)

Arguments

CIs

a numeric vector or matrix of confidence interval values for a given parameter value, where the first element/column indicates the lower confidence interval and the second element/column the upper confidence interval. If a vector

parameter

a numeric scalar indicating the fixed parameter value

Examples

CIs <- matrix(NA, 100, 2)
for(i in 1:100){
   dat <- rnorm(100)
   CIs[i,] <- t.test(dat)$conf.int
}
