Calculate the power for Sensitivity Index

Share:

Description

Ho: μ_1 = μ_2

Ha: μ_1 is not equal to μ_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

1
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.
