Rmetrics - Nonlinear and Chaotic Time Series Modelling R package fNonlinear version 4052.83 CRAN Task View: Finance (https://CRAN.R-project.org/view=Finance) CRAN Task View: TimeSeries (https://CRAN.R-project.org/view=TimeSeries) Provides a collection of functions for testing various aspects of univariate time series including independence and neglected nonlinearities. Further provides functions to investigate the chaotic behavior of time series processes and to simulate different types of chaotic time series maps.
