GEOMETRIC MEAN

GEOMETRIC MEAN (LET)

Let Subcommand

Compute the geometric mean for a variable.

The geometric mean is defined as:

LET <par> = GEOMETRIC MEAN <y1>             <SUBSET/EXCEPT/FOR qualification>
where <y1> is the response variable;
            <par> is a parameter where the computed geometric mean is stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

LET A = GEOMETRIC MEAN Y1
LET A = GEOMETRIC MEAN Y1 SUBSET TAG > 2

Support for the geometric mean has been added to the following plots and commands:
GEOMETRIC MEAN PLOT
BOOTSTRAP GEOMETRIC MEAN PLOT
JACKNIFE GEOMETRIC MEAN PLOT
CROSS TABULATE GEOMETRIC MEAN PLOT
INTERACTION GEOMETRIC MEAN PLOT
INFLUENCE GEOMETRIC MEAN PLOT
TABULATE GEOMETRIC MEAN
CROSS TABULATE GEOMETRIC MEAN
LET ... = CROSS TABULATE GEOMETRIC MEAN
