power.calc: Calculates the empirical and theoretical power

In agaye/ESPRESSO.G: Power Analysis and Sample Size Calculation for a model with a main effect genetic covariate

Description

The function determines the empirical and theoretical power. The empirical power is the proportion of simulations in which the z-statistic for the parameter of interest exceeds the z-statistic for the desured level if statistical significance. The theoretical power is the power of the study.

Usage

power.calc(pval = 1e-04, z.values = NULL, mean.model.z = NULL)

Arguments

pval	cut-off p-value defining statistical significance.
z.values	z-statistic of the determinant.
mean.model.z	mean z-statistic of the environmental determinant.

Value

a list that contains the computed empirical power and theoretical power.
