%description
This R package provides an implementation of multivariate extensions of a
well-known fractal analysis technique, Detrended Fluctuations Analysis
(DFA; Peng et al., 1995<doi:10.1063/1.166141>), for multivariate time
series: multivariate DFA (mvDFA). Several coefficients are implemented
that take into account the correlation structure of the multivariate time
series to varying degrees. These coefficients may be used to analyze long
memory and changes in the dynamic structure that would by univariate DFA.
Therefore, this R package aims to extend and complement the original
univariate DFA (Peng et al., 1995) for estimating the scaling properties
of nonstationary time series.
