Description: Implements confidence interval and sample size methods that 
    are especially useful in psychological research. The methods can be 
    applied in 1-group, 2-group, paired-samples, and multiple-group designs
    and to a variety of parameters including means, medians, proportions, 
    slopes, standardized mean differences, standardized linear contrasts 
    of means, plus several measures of correlation and association. 
    Confidence interval and sample size functions are given for single 
    parameters as well as differences, ratios, and linear contrasts of
    parameters. The sample size functions can be used to approximate the 
    sample size needed to estimate a parameter or function of parameters 
    with desired confidence interval precision or to perform a variety of
    hypothesis tests (directional two-sided, equivalence, superiority, 
    noninferiority) with desired power. For details see: Statistical Methods
    for Psychologists, Volumes 1 – 4, <https://dgbonett.sites.ucsc.edu/>.
