In JBTools: Misc Small Tools and Helper Functions for Other Code of J. Buttlar

Description

isSeriesConstant checks whether a series is constant (up to a certain degree).

Usage

isSeriesConstant(x, tresh.const = 1e-12, ratio.const = 0.05)

Arguments

x	numeric vector: series to test.
tresh.const	numeric: maximum deviation allowed which is still considered to be constant.
ratio.const	numeric: ratio of the series which is allowed to be not constant for the whole series to be still considered to be constant.

Details

isSeriesConstant checks whether the amount of values deviating from the median of x for a higher value than tresh.const is bigger than ratio.const.

Value

logical: TRUE if series is constant, FALSE otherwise.
