Empirical detection robustness method suggested by Serlin (2000)

Description

Hypothesis test to determine whether an observed empirical detection rate, coupled with a given robustness interval, statistically differs from the population value. Uses the methods described by Serlin (2000) as well to generate critical values (similar to confidence intervals, but define a fixed window of robustness). Critical values may be computed without performing the simulation experiment (hence, can be obtained a priori).

Usage

Serlin2000(p, alpha, delta, R, CI = 0.95)

Arguments

p	(optional) a vector containing the empirical detection rate(s) to be tested. Omitting this input will compute only the CV1 and CV2 values, while including this input will perform a one-sided hypothesis test for robustness
alpha	Type I error rate (e.g., often set to .05)
delta	(optional) symmetric robustness interval around alpha (e.g., a value of .01 when alpha = .05 would test the robustness window .04-.06)
R	number of replications used in the simulation
CI	confidence interval for alpha as a proportion. Default of 0.95 indicates a 95% interval
