# R package pvar

This package deals with the $$p$$-variation of the sample. Nonetheless, it could be used for to calculate $$p$$-variation for arbitrary piecewise monotonic function as well. See:

• pvar - it is a function that calculates the $$p$$-variation of the sample.
• PvarBreakTest - it is functions that performs a test of multiple changes in a sequence of independent observations. This is one of the example of $$p$$-variation use in statistics.
