delta | double | The minimum detectable difference. |
standardDeviation | double | The difference standard deviation. |
proportion | double | The proportion of observations in the second group /// when compared to the first group. A proportion of 2:1 results in twice more /// samples in the second group than in the first. Default is 1. |
power | double | The desired power level. Default is 0.8. |
alpha | double | The desired significance level. Default is 0.05. |
hypothesis | TwoSampleHypothesis | The alternative hypothesis (research hypothesis) to be tested. |
