Physical/pictoral interpretation of higher-order moments
Cross Validated Asked by James Koppel on November 24, 2021
I’m preparing a presentation about parallel statistics. I plan to illustrate the formulas for distributed computation of the mean and variance with examples involving center of gravity and moment of inertia. I’m wondering if there is a physical interpretation of the third or higher central moments that I can use to help illustrate the general formula.
One Answer
If by graphical representation you meant histograms, I gather this is the best approach to provide a visual display of the moments. Please be aware we cannot specify any value for kurtosis. But there is a formula to provide kurtosis under random simulations.
Being k = kurtosis, sk = skewness, the formula is: k > sk^2 +1.
Below, a histogram with the specifications.
