NettetIn stochastic processes, chaos theory and time series analysis, detrended fluctuation analysis ( DFA) is a method for determining the statistical self-affinity of a signal. It is useful for analysing time series that appear to be long-memory processes (diverging correlation time, e.g. power-law decaying autocorrelation function) or 1/f noise . NettetAug 7, 2016 at 3:18. It depends on how you measure standard deviation: if it is the root-mean-square difference from the mean of the data set, then you would expect detrending to make a possibly substantial difference; if it is the rms difference from the prediction of the linear regression, then you would expect detrending to make no difference.

It is useful for analysing time series that appear to be long-memory processes (diverging correlation time, e.g. power-law decaying autocorrelation function) or 1/f noise. The obtained exponent is similar to the Hurst exponent, except that DFA may also be applied to … NettetTrend() also provides the time series of the detrended ensemble mean forecasts.
