Greetings,
I'm going to use the  Statistics::Shannon module in my application.
Here I have computed simple perl file which compare the difference between two sets of data.
Please suggest me, Is that the correct way of comparing values using shannon index.
I will be greateful, If anyone can update me with more details.
Here is the link for the  Shannon Module for your quick reference.
What about the  evenness method in that module.Shall I need to consider that similarity of frequencies also ? in order to compute these differences ? 
#!c:\perl\bin\perl

use strict;
use warnings;
use Statistics::Shannon;
use Data::Dumper;
my $data1=[3,1,3,2,3];
my $data2=[4,1,3,2,3];
my $base_index=2;

my $shannon1=Statistics::Shannon->new($data1,$base_index);
my $shannon2=Statistics::Shannon->new($data2,$base_index);

my $output1=$shannon1->index;
my $output2=$shannon2->index;

print $output1."\t".$output2;
print "\tNot match" if( $output2 != $output1);
