RemarksA multivariate sample is simply a sample in which more than one number is associated with each data point. A study which records only the height of each subject could use the Sample class to store its data, but a study which records the income and height of each subject should use MutlivariateSample class. In addition to descriptive statistics, this class offers tests for studying the associations between the recorded variables, and routines for fitting the sample to a model.
