GEOMEANX - Daxplained

GEOMEANX is a DAX function that returns the geometric mean of an expression evaluated for each row in a table.

Syntax

GEOMEANX(
   Table,
   Expression
)

Argument	Properties	Description
Table		Table over which the Expression will be evaluated.
Expression		Expression to evaluate for each row of the table.

A decimal number.

The GEOMEANX function takes as its first argument a table, or an expression that returns a table. The second argument is a column that contains the numbers for which you want to compute the geometric mean, or an expression that evaluates to a column.
Only the numbers in the column are counted. Blanks, logical values, and text are ignored.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

The following computes the geometric mean of the ReturnPct column in the Investments table:

= GEOMEANX( Investments, Investments[ReturnPct] + 1 )
