Moving average or running mean

Question

Is there a SciPy function or NumPy function or module for Python that calculates the running mean of a 1D array given a specific window?

Answer 1

For a ready-to-use solution, see https://scipy-cookbook.readthedocs.io/items/SignalSmooth.html. It provides running average with the flat window type. Note that this is a bit more sophisticated than the simple do-it-yourself convolve-method, since it tries to handle the problems at the beginning and the end of the data by reflecting it (which may or may not work in your case...).

To start with, you could try:

a = np.random.random(100)
plt.plot(a)
b = smooth(a, window='flat')
plt.plot(b)
