Hello, bug collector!
Module: Statistics-Basic-1.6602
This is perl, v5.10.1 built for MSWin32-x86-multi-thread
(with 2 registered patches, see perl -V for more detail)
Copyright 1987-2009, Larry Wall
Binary build 1006 [291086] provided by ActiveState http://www.ActiveState.com
Built Aug 24 2009 13:48:26
Operating system: Windows XP SP3
At least stddev() and variance () functions are working erroneously.
Example (just from manual to module):
use Statistics::Basic qw(:all nofill);
@arr=[1,2,3];
my $median = median( @arr);
my $mean = mean( @arr);
my $variance = variance(@arr);
my $stddev = stddev(@arr);
print "deviance=$stddev, median=$median, variance=$variance, mean=$mean\n";
The output will be:
deviance=0.82, median=2, variance=0.67, mean=2
What is wrong: deviance=1.0, variance=1.0
Sincerely yours, Youri
