Returns the mean value of all the elements of array «X», averaged over index «I». The full declaration of the function is
- Average(X: Numeric[I]; I: Index)
The array «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.
