Power analyses and sample size calculations are important parts of many research projects. Often, before data are even collected, it is necessary to calculate and justify the required sample size for ...

Some existing nonparametric two-sample tests for equality of multivariate distributions perform unsatisfactorily when the two sample sizes are unbalanced. In particular, the power of these tests tends ...

Mainland and Sutcliffe [1953] and Bennett and Hsu [1960] have calculated the power of the exact conditional (Fisher-Irwin) test for differences between proportions. We have performed similar ...

Statistics is difficult, and choosing the proper tools becomes more challenging as experiments become more complex. That's why it's not uncommon for large genetics or epidemiological studies to have a ...
