Moment
Advanced Analysis Library Only
AnalysisLibErrType Moment (double inputArray[], ssize_t 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 Code
/* 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);
