| Detrend Function during detrended fluctuation analysis in nonlinear analysis [ Reply ] By: louis HOGNON on 2019-12-16 14:01 | [forum:47284] |

Hello Thank you for the package which is really top. I would like to know if in the DFA (detrended fluctuation analysis) part, the RR signal is processed and that we remove its general tendency by a detrend function like the pracma package offers or not? Because by calculating the fluctuations on a certain time scale, one is strongly influenced by the fact that the signal has a constant trend on longer time scales. This trend is unlikely to be part of a process on the time scale of this window and can be removed by subtracting the linear trend in the window. In this way, processes on scales larger than the size of the given window will only marginally influence the fluctuation function thank you so much |
