The function smd.t.test enhances the output of the independent groups t-test, including the standardized mean difference or Cohen's d, and the introduction of the ODDSMD plot, which displays the Overlapping Density Distributions of the two groups as well as a visual display of the mean difference and standardized mean difference. Other functions provide for the t-test from descriptive statistics, color plotting, color histogram, a calibrated power curve plotted with colors, and a comprehensive regression analysis from one statement. Use rad for a one statement read and initial processing of csv data, and the function out to write the csv file. The function help.me provides a help system that suggests specific analyses by providing the name of the relevant functions for a specific topic.
