Equivalence and Non-inferiority Procedures included in version 3.0.

For non-inferiority- and equivalence hypotheses it's quite common to use confidence intervals instead of one- and two one-sided tests, respectively. The confidence level is then chosen to correspond to the significance level of the test. In the following situations the sample size can be calculated using the confidence interval approach.



 

  • Equivalence, Confidence Interval
    • Diference of Means, t-distribution
    • Ratio of Medians, Lognormal distribution
    • Difference of Proportions, Binomial distribution
    • Difference of Paired Proportions
    • Comparison of Survival, Exponential distribution
  • Bioequivalence, Two-way Crossover Design
    • Test approach
