Compute the geometric mean, geometric standard deviation, and geometric
Kirkwood's proposal for the geometric coefficient of variation (GCV) is not generally used. Instead, the accepted definition of the GCV is GCV = sqrt(exp(σ 2) – 1), which is the definition that is used in SAS. The estimate for the GCV is sqrt(exp(s 2) – 1). You can use these formulas to compute the geometric statistics for any positive data.
