VARIANCE Function

VARIANCE, a numeric function, returns a value that approximates the variance of its arguments.

argument

is a numeric argument.

argument can be an array; for example,

FUNCTION VARIANCE (ARRAY1(ALL))

returns a value that approximates the variance of the elements of the array ARRAY1.

The returned value is the approximation of the variance of the argument series.

If there is only one argument, or if every argument is a variable occurrence data item and the

total number of occurrences for all of them is one, the returned value is zero; otherwise, the returned

value is the square of the standard deviation of the argument series; that is:
