Calculates the power and sample size for Cochran-Mantel-Haenszel tests. 
    There are also several helper functions for working with probability,
    odds, relative risk, and odds ratio values.

Calculates the sample size needed for evaluating a diagnostic test based on sensitivity, specificity, prevalence, and desired precision. Based on Buderer (1996) <doi:10.1111/j.1553-2712.1996.tb03538.x>.

Calculates sample size for various scenarios, such as sample size
    to estimate population proportion with stated absolute or relative
    precision, testing a single proportion with a reference value, to estimate
    the population mean with stated absolute or relative precision, testing
    single mean with a reference value and sample size for comparing two
    unpaired or independent means, comparing two paired means, the sample size
    For case control studies, estimating the odds ratio with stated precision,
    testing the odds ratio with a reference value, estimating relative risk with
    stated precision, testing relative risk with a reference value, testing
    a correlation coefficient with a specified value, etc.

To determine sample size or power for case-control studies to be analyzed using logistic regression.

Sample size requirements calculation
        using three different Bayesian criteria in the
        context of designing an experiment to estimate a normal mean or
        the difference between two normal means.  Functions for
        calculation of required sample sizes for the Average Length
        Criterion, the Average Coverage Criterion and the Worst Outcome
        Criterion in the context of normal means are provided.
        Functions for both the fully Bayesian and the mixed
        Bayesian/likelihood approaches are provided.
