Netteta n is the n-th element of incoming data, a m is the element from which we start averaging, a n − m ^ is the avarage from m-th to n-th element, a n + 1 − ( m + 1) ^ is the avarage from (m+1)-th to (n+1)-th element. So, if we initially have a m, a m + 1, a m + 2, …, a n, an average of n − m elements can be easily calculated. That is. NettetA simple way to achieve this is by using np.convolve.The idea behind this is to leverage the way the discrete convolution is computed and use it to return a rolling mean.This can be done by convolving with a sequence of np.ones of a length equal to the sliding window length we want.. In order to do so we could define the following function:
