Functions for parametric and nonparametric statistics

Parametric statistics are computed by the CHISQ_TEST_AGG and CHISQ_TEST_S_AGG stored procedures, and several T_TEST stored procedures. Nonparametric statistics are computed by the CHISQ_TEST, the MWW_TEST, the SPEARMAN_CORR, and the WILCOXON_TEST stored procedures.

All stored procedures consist of a mandatory one-string parameter that contains pairs of <parameter>=<value> entries. These entries are separated by a comma. The data type of the parameter is VARCHAR(any).

Valid <parameter>=<value> entries are listed in the parameter descriptions for each stored procedure.
