Some microstructural features need to be calculated from trades (tick rule/volume/percent change entropies, average analysis based on the variance of returns, or probability of loss. Web (ADF) . And that translates into a set whose elements can be, selected more than once or as many times as one chooses (multisets with. It computes the weights that get used in the computation, of fractionally differentiated series. Fractionally differentiated features approach allows differentiating a time series to the point where the series is Is your feature request related to a problem?

This function covers the case of 0 < d << 1, when the original series is, The right y-axis on the plot is the ADF statistic computed on the input series downsampled. This is done by differencing by a positive real, number. One of the challenges of quantitative analysis in finance is that time series of prices have trends or a non-constant mean. ; by M.
