The Determination of Partial Moments

Abstract
In statistical decision theory, computations often involve the partial moments of a random variable. Several methods for determining partial moments are discussed, including direct calculation, the use of general formulas which apply to entire families of distributions, and the use of partial moment generating functions. Using these methods, formulas (some involving recursive relationships) are developed for the partial moments of a number of frequently encountered distributions and compared with the corresponding formulas for complete moments.
