Var (MDX)
Returns the sample variance of a numeric expression evaluated over a set, using the unbiased population formula (dividing by n).
Syntax
Var(Set_Expression [ ,Numeric_Expression ] )
Arguments
Set_Expression
A valid Multidimensional Expressions (MDX) expression that returns a set.Numeric_Expression
A valid numeric expression that is typically a Multidimensional Expressions (MDX) expression of cell coordinates that return a number.
Remarks
The Var function returns the unbiased variance of a specified numeric expression evaluated over a specified set.
The Var function uses the unbiased population formula, and the VarP function uses the biased population formula.
