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.
The VarP function returns the biased variance of a specified numeric expression, evaluated over a specified set.
The VarP function uses the biased population formula, while the Var function uses the unbiased population formula.
