Description

Estimate N on the basis of one pilot sample.

Usage

n_locshift_one(sample, alpha, power, delta, q)

Arguments

sample	pilot data
alpha	Type I error probability
power	1 - Type II error probability, the desired statistical power
delta	numeric value, location shift parameter δ
q	size of group0 relative to total sample size.

Value
