Time Series Costationarity Determination R package costat version 2.4.1 CRAN Task View: TimeSeries (https://CRAN.R-project.org/view=TimeSeries) Contains functions that can determine whether a time series is second-order stationary or not (and hence evidence for locally stationarity). Given two non-stationary series (i.e. locally stationary series) this package can then discover time-varying linear combinations that are second-order stationary. Cardinali, A. and Nason, G.P.
