# Moment

Advanced Analysis Library Only

AnalysisLibErrType Moment (double inputArray[], int numberOfElements, int order, double *moment);

## Purpose

Calculates the moment about the mean of the input array with the specified order. Moment uses the following formulas to find the moment:

where

### Example

/* Generate an array with random numbers and determine its skewness (third-order moment) and its kurtosis (fourth-order moment). */
double x[200], skew, kurtosis;
n, order;
n = 200;
Uniform (n, 17, x);
order = 3;
Moment (x, n, order, &skew);
order = 4;
Moment (x, n, order, &kurtosis);

## Parameters

Input
Name | Type | Description
inputArray | double-precision array | Input array used to compute the moment about the mean.
numberOfElements | integer | Number of elements used to compute the moment about the mean.
order | integer | Moment order.
| Note order must be greater than zero. If this value is less than zero, Moment returns an error code and does not calculate the mean.
Default Value: 3.
Output
Name | Type | Description
moment | double-precision | Moment about the mean.

## Return Value

Name | Type | Description
status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants.
