Compute the geometric mean, sd, and CV

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.
