Factorial moment measure
MATHEMATICAL QUANTITY, FUNCTION OR, MORE PRECISELY, MEASURE THAT IS DEFINED IN RELATION TO MATHEMATICAL OBJECTS KNOWN AS POINT PROCESSES
In probability and statistics, a factorial moment measure is a mathematical quantity, function or, more precisely, measure that is defined in relation to mathematical objects known as point processes, which are types of stochastic processes often used as mathematical models of physical phenomena representable as randomly positioned points in time, space or both. Moment measures generalize the idea of factorial moments, which are useful for studying non-negative integer-valued random variables.
