# MomentEvaluate

MomentEvaluate[mexpr, dist]
evaluates formal moments in the moment expression mexpr on the distribution dist.

MomentEvaluate[mexpr, list]
evaluates formal moments and formal sample moments in mexpr on the data list.

MomentEvaluate[mexpr, dist, list]
evaluates formal moments on the distribution dist and formal sample moments on the data list.

## DetailsDetails

• A moment expression is an expression involving formal moments and formal sample moments.
• A formal moment is an expression of the form:
•  Moment[r] formal r moment CentralMoment[r] formal r central moment FactorialMoment[r] formal r factorial moment Cumulant[r] formal r cumulant
• A formal sample moment is an expression of the form:
•  PowerSymmetricPolynomial[r] formal r power symmetric polynomial AugmentedSymmetricPolynomial[{r1,r2,...}] formal augmented symmetric polynomial
• For a sample moment expression is taken to be the length of the list of data.
• MomentEvaluate[mexpr, ..., n] assumes that n is taken to be the length of the list of data.
