QT.crossover | R Documentation |
Ho: \mu_1 -\mu_2 = 0
Ha: \mu_1 -\mu_2 = d
The test is finding the treatment difference in QT interval for crossover design . d is not equal to 0, which is the difference of clinically importance.
QT.crossover(alpha, beta, pho, K, delta, gamma)
alpha |
significance level |
beta |
power = 1-beta |
pho |
pho=between subject variance |
K |
There are K recording replicates for each subject. |
delta |
|
gamma |
