Sensitivity.Index {TrialSize} | R Documentation |
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.
Sensitivity.Index(alpha, n, deltaT)
alpha |

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. |
