Sensitivity.Index: Calculate the power for Sensitivity Index

Description

Ho: \(\mu_1 = \mu_2 \)

Ha: \(\mu_1\) is not equal to \(\mu_2\)

The test is finding the treatment difference in QT interval.

d is not equal to 0, which is the difference of clinically importance.

Usage

Sensitivity.Index(alpha, n, deltaT)

Arguments

alpha

significance level

n

sample size n

deltaT

a measure of change in the signal-to-noise ratio for the population difference, which is the sensitivity index of population difference between regions.
