I just star working with Rstudio.
At this moment me and my partner’s in Evora University need something specifics - DFA - Detrended Fluctuation Analysis. This test its available in R.
Now i present to you more information about the Test:
Description - Performs a detrended fluctuation analysis (DFA) and estimates the scaling exponent from the results. DFA is used to characterize long memory dependence in stochastic fractal time series.
Usage - DFA(x, detrend=“poly1”, sum.order=0, overlap=0, scale.max=trunc(length(x)/2), scale.min=NULL, scale.ratio=2, verbose=FALSE)
