npcv: Non-parametric coefficient of variation
In lgatto/MSnbase: Base Functions and Classes for Mass Spectrometry and Proteomics
npcv R Documentation
Non-parametric coefficient of variation
Description
Calculates a non-parametric version of the coefficient of
variation where the standard deviation is replaced by the median
absolute deviations (see mad for details) and
divided by the absolute value of the mean.
Note that the mad of a single value is 0 (as opposed to
NA for the standard deviation, see example below).
Usage
npcv(x, na.rm = TRUE)
Arguments
x
A numeric.
na.rm
A logical (default is TRUE indicating
whether NA values should be stripped before the computation
of the median absolute deviation and mean.
Value
A numeric.
