SYNOPSIS

my @x = (1,4,5,3,7,2,4);

my($tmean) = tmean(\@x);

my($win) = win(\@x);

FUNCTIONS

win

my($win) = win(\@x,$gamma);

Return the gamma Winsorized mean.  If gamma is not specified, it defaults to 0.2.

tmean

my($tmean) = tmean(\@x,$tr);

Return the trimmed mean.  If $tr is not specified, it defaults to 0.2.

mean

my($mean) = mean(\@x);

Although not a robust measure of location, it is useful for comparison as well as used internally in the computation
of some robust methods. This returns the mean of the array @x.

hd

my($est) = hd(\@x, $q)

The Harell-Davis Estimator for the quantile $q.

median
