tpower2g2: Power Function Of The Two Sample Test

In joemckean/mathstat: Introduction to Mathematical Statistics R Package

Description

computes power function for two-sample t-testfor the alternative mu1 > mu2. This test is discussed in Example 4.6.2, page 278. Power functions for two-sample t-tests are discussed in Example 8.3.3 on page 493.

Usage

tpower2g2(n, m, Delta, sig, alpha)

Arguments

n	a number, a sample size of first sample related to mu1
m	a number, a sample size of second sample related to mu2
Delta	a number, Delta = mu1 - mu2 is the argument for the power function.
sig	a number, common standard deviation of the 2 populations
alpha	a number, the significance level of the test

Value

a number, gamma the power of the t-test to dectect delta
