CV: Compute CV

Description

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

Usage

CV(x, na.rm = FALSE)

Arguments

x

numeric vector with positive numbers.

na.rm

logical. Should missing values be removed?

Value

CV value.

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.

Examples

# NOT RUN {
## 5% outliers
out <- rbinom(100, prob = 0.05, size = 1)
sum(out)
x <- (1-out)*rnorm(100, mean = 10, sd = 2) + out*25
CV(x)
medCV(x)
iqrCV(x)
# }
