A general method that can be used for the study of a discrete and finite random variable is presented. The method is based on the introduction of a transform of the probability density function, called gamma-transform. A formula for computing the factorial moments directly from the gamma-transform is derived. Moreover, it is shown how the gamma-transform can be simply derived owing to its physical meaning for several combinatorial problems. Examples and applications relevant for computer science are provided.

Abstract
A general method that can be used for the study of a discrete and finite random variable is presented. The method is based on the introduction of a transform of the probability density function, called gamma-transform. A formula for computing the factorial moments directly from the gamma-transform is derived. Moreover, it is shown how the gamma-transform can be simply derived owing to its physical meaning for several combinatorial problems. Examples and applications relevant for computer science are provided.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
