WebIn probability theory and statistics, a standardized moment of a probability distribution is a moment (normally a higher degree central moment) that is normalized. The normalization is typically a division by an expression of the standarddeviation which renders the moment scale invariant. Moments WebThe applications of moments of order statistics are well-known in the statistical literature; see [ 3, 4, 5 ]. Explicit expressions for order statistics moments were determined by [ 6 ].
