Calculate Coefficient of Variation

Usage

cv(x, na.rm = FALSE)

Arguments

x

Input vector to compute CV for.

na.rm

boolean to remove NA. default is FALSE

Value

CV of x. Standard deviation divided by mean. If you want % you'll need to multiply by 100

Details

The coefficient of variation is calculated as: $$CV = \frac{\sigma}{\mu}$$

where:

  • \(\sigma\) = standard deviation

  • \(\mu\) = mean
