In this article we study sample size calculation methods for the asymptotic van Elteren test. Because the existing methods are only applicable to continuous data without ties, in this article we develop a new method that can be used on ordinal data. The new method has a closed form formula ...

Pre-study calculation of the sample size is important; if a sample size is too small, one will not be able to detect an effect, while a sample that is too large may be a waste of time and money. Methods to calculate the sample size are explained in statistical textbooks, but because ...

Several sample size calculation methods while controlling FDR have been proposed in microarray experiments. For example, Liu and Hwang [14] developed a method to calculate sample size given a desired power and a controlled level of FDR by finding the rejection region for the test procedure and he...
