geomean: Compute the geometric mean, sd, and CV

In PKNCA: Perform Pharmacokinetic Non-Compartmental Analysis

Compute the geometric mean, sd, and CV

Description

Compute the geometric mean, sd, and CV

Usage

geomean(x, na.rm = FALSE)

geosd(x, na.rm = FALSE)

geocv(x, na.rm = FALSE)

Arguments

x	A vector to compute the geometric mean of
na.rm	Should missing values be removed?

Value

The scalar value of the geometric mean, geometric standard deviation, or geometric coefficient of variation.

Functions

• geosd(): Compute the geometric standard deviation, exp(sd(log(x))).

• geocv(): Compute the geometric coefficient of variation, sqrt(exp(sd(log(x))^2)-1)*100.
