Compute the absolute coefficient of variationcv as proposed by Karl Pearson, which is given by the division of standard deviation by the mean. The CV reflects a normalized measure of the dispersion of a given probability distribution. Conversely, distributions with $cv < 1$ are considered low-variance, while those with $cv > 1$ high-variance.
Usage
cv(x, na.rm = TRUE)
## S3 method for class 'ANY':
cv(x, na.rm = TRUE)
Arguments
x
A numeric vector.
na.rm
A logical value, default is FALSE
Value
The coefficient of variation.

Details
$\frac{sd(x)}{mean(x)} = cv$, which is the inverse of signal-to-noise ratio.
