LPTime-package: Algorithm to analyze nonlinear time series data

Description

This package provides general tools for analyzing non-Gaussian nonlinear multivariate time series models. The algorithm is described in the paper Nonlinear Time Series Modeling by LPTime, Nonparametric Empirical Learning., by Mukhopadhyay and Parzen (2013). The central idea behind LPTime time series modelling algorithm is to convert the original univariate time series $X(t)$ into $$\mbox{Vec}(X)(t) = [\mbox{T}_{1}[X](t),\ldots, \mbox{T}_{k}[X](t)]^{T}$$ via tailor-made orthonormal (mid-rank based) nonlinear transformation that automatically tackles heavy-tailed process (such as daily S&P 500 return data) by injecting robustness in the time series analysis, applicable for discrete and continuous time series data modelling. The main functions are as follows: (1) LPTime; (2) LPiTrack
