Will a k-period weighted average produce a lower mean square error (MSE) when making predictions than a weighted average derived from k minus 1 periods? If so, why or why not?© BrainMass Inc. brainmass.com March 4, 2021, 6:22 pm ad1c9bdddf
This solution is provided in 92 words in an attached .doc file. It provides the equation for mean square error, including that in relation to a Fourier series. This is explained and it is shown how k is related to the size of mean square error.
