    Last updated for version 2.01, Decemver 22, 2006

SYNOPSIS

    This document provides a general introduction to the SGT
    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();
