Returned Value
- The returned value is the approximation of the variance of the
argument-1 series.
- The returned value is defined as the square of the standard deviation of the
argument-1 series.
- If the
argument-1 series consists of only one value, or if the
argument-1 series consists of all variable occurrence data items and the total number of occurrences for all of them is one, the returned
value is zero.
