Returns the mean value of all the elements of array X, averaged over index I.
Declaration
Average( X : Numeric[I] ; I : Index )
Notes
X is evaluated in context. Thus, if you use Average to sum over the Run index, you may encounter a potential confusion, since Average(A,I) will be summing the Mid-value across I, not the sample. To sum over the Run index, use the Mean function, unless your intention really is to Sum the mid-value.
