Other statistical methods


The Procedure Library covers many other areas of statistics, including analysis of repeated measurements or of circular data, exact tests, sample re-use, survival analysis, Bayesian methods, and the assessment of species diversity and abundance:


ANTORDER
assesses order of ante-dependence for repeated measures data

ANTTEST
calculates overall tests based on a specified order of ante-dependence
