computePowerBySampleSize: Compute the Power Over a Grid of Sample Size Values

Description

Computes the power over a grid of sample size values.

Usage

computePowerBySampleSize(V, Delta, min_Delta, alpha = 0.05, sample_size_grid)

Arguments

V

The covariance matrix of mean EDTR estimators.

Delta

The vector of effect sizes with a zero indicating the best EDTR.

min_Delta

The minimum desired detectable effect size.

alpha

The Type I error rate for not including the true best EDTR.

sample_size_grid

The vector of sample sizes

Value

A vector of power for each sample size in the given grid.

Details

It employs common random variables to reduce the variance. See computePower for more details.
