morie_madn is the book's MADN, MAD / 0.6745. morie_mad_rescaled
uses R's mad() constant 1.4826, which is what WRS relies on – the
two differ in the fifth significant figure and the estimators ported
from WRS use the R one. morie_mad_median_rule is the Hampel
identifier of eq. (2.14): declare X an outlier when
|X - M| / MADN > 2.24.
Usage
morie_mad(x)
morie_madn(x)
morie_mad_rescaled(x, constant = 1.4826)
morie_mad_median_rule(x, crit = 2.24)Value
morie_mad, morie_madn, morie_mad_rescaled numbers;
morie_mad_median_rule a list with median, madn, ratio,
is_outlier, outliers, n_outliers
Examples
V <- c(1, 2, 3, 4, 5, 6, 7, 8)
