EDR {SimDesign}

Compute the empirical detection/rejection rate for Type I errors and Power

Description

Computes the detection/rejection rate for determining empirical Type I error and power rates using information from p-values.

Usage

EDR(p, alpha = 0.05, unname = FALSE)

Arguments

p

a numeric vector or matrix/data.frame of p-values from the desired statistical estimator. If a matrix, each statistic must be organized by column, where the number of rows is equal to the number of replications

alpha

the detection threshold (typical values are .10, .05, and .01). Default is .05

unname

logical; apply unname to the results to remove any variable names?
