In probability theory and statistics, a central moment is a moment of a probability distribution of a random variable about the random variable's mean; that is, it is the expected value of a specified integer power of the deviation of the random variable from the mean. The various moments form one set of values by which the properties of a probability distribution can be usefully characterized. Central moments are used in preference to ordinary moments, computed in term… WebFeb 1, 2024 · 5. Conclusions. In this paper, an iterative method for the central moments of the matrix Fisher distribution defined on SO (3) is introduced up to an arbitrary order. Although this paper only focuses on the sample space SO (3), the method can be generalized to O (n) and SO (n) with minor modifications, considering that they share the …
