Package for time series analysis and computational finance
Routines for the analysis of nonlinear time series. This work is largely inspired by the TISEAN project, by Rainer Hegger, Holger Kantz and Thomas Schreiber: http://www.mpipks-dresden.mpg.de/~tisean/
Implements nonlinear autoregressive (AR) time series models. For univariate series, a non-parametric approach is available through additive nonlinear AR. Parametric modeling and testing for regime switching dynamics is available when the transition is either direct (TAR: threshold AR) or smooth (STAR: smooth transition AR, LSTAR). For multivariate series, one can estimate a range of TVAR or threshold cointegration TVECM models with two or three regimes. Tests can be conducted for TVAR as well as for TVECM (Hansen and Seo 2002 and Seo 2006).
Functions for statistical analysis, prediction and control of time series.
The Direct Filter Approach (DFA) provides efficient estimates of
signals at the current boundary of time series in real-time. For
that purpose, one-sided ARMA-filters are computed by minimizing
customized error criteria. The DFA can be used for estimating
either the level or turning-points of a series, knowing that both
criteria are incongruent. In the context of real-time turning-
point detection, various risk-profiles can be operationalized,
which account for the speed and/or the reliability of the one-
