Description: Implements confidence interval and sample size methods that are especially
    useful in psychological research but are also useful in educational, social science, 
    business, and biological research. This package includes more than 100 confidence 
    interval functions and more than 80 sample size functions for 1-group, 2-group, 
    paired-samples, and multiple-group designs and for a variety of parameters including 
    means, medians, proportions, slopes, standardized mean differences, standardized 
    linear contrasts of means, and several measures of correlation and association. 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 about these methods see:
