rsd: Computing relative standard deviation of a vector
Description
This function computes the relative standard deviation (also known as coefficient of variation) of a numeric vector defined
as the ratio of the standard deviation to the mean of the vector elements, expressed as percentage
Usage
rsd(v)
Arguments
v
a numeric vector
Value
the value of the coefficient of variation of the input vector expressed as a percentage and rounded to two
decimal places
Details
the coefficient of variation shows the extent of variability in relation to mean of the population.
It is expressed as a percentage. Lower values indicate lower variability.
