NOT wrapper — Narrowest-Over-Threshold — not

Wraps the not package for changepoint detection via the Narrowest-Over-Threshold method. The contrast determines what change is detected: piecewise-constant mean (default), mean and variance, or (continuous or discontinuous) piecewise-linear trend.

Usage

not_wrapper(x, contrast = "pcwsConstMean", seed = NULL, ...)

Arguments

x: A numeric vector.
contrast: Contrast type. One of "pcwsConstMean", "pcwsLinContMean", "pcwsLinMean", "pcwsConstMeanVar". Defaults to "pcwsConstMean".
seed: Optional seed for reproducibility.
...: Additional arguments passed to not::not().

Value

A ggcpt object whose change_in reflects the contrast: "mean", "meanvar", or "slope".
