Calculate unnormalized moments of an ndarray. Another name for these things is that they are the expected value of polynomials. The first unnormalized moment is just the mean, the second is the expected value of x^2, the 3rd is E[x^3], etc. Using this data, you can compute any polynomial statistic like variance, kurtosis, or skewness using the method of moments (aka linearity of expectation).
