Compute CV

The functions compute coefficient of variation (CV) as well as two robust versions of the CV.

Keywords
univar
Usage
CV(x, na.rm = FALSE)
Arguments
x

numeric vector.

na.rm

logical. Should missing values be removed?

Details

The functions compute the (classical) CV as well as two robust variants.

medCV uses the (standardized) MAD instead of SD and median instead of mean.

iqrCV uses the (standardized) IQR instead of SD and median instead of mean.

Value

CV value.
