    Last updated for version 2.01, December 22, 2006

SYNOPSIS
    This document provides a general introduction to the SGT
    (Simple Good Turing smoothing) package.

DESCRIPTION

	This Perl module implements the Simple Good Touring (SGT) algorithm 
    for smoothing of probabilistic values developed by William Gale and 
    Geoffrey Sampson. 

    The algorithm is described in the following article: 
    <http://l2r.cs.uiuc.edu/~danr/Teaching/CS598-05/Papers/Gale-Sampson-smoothgoodturing.pdf>
    
    Basic usage:

	    use Statistics::Smoothing::SGT
		my $sgt = new SGT($frequencyClasses, $total);
		$sgt->calculateSGTValues();
  		$probabilities = $sgt->getProbabilities();
  		$newFrequencies = $sgt->getNewFrequencies();
  		$nBar = $sgt->getNBar();
