Statistics::Basic::MedUser3Contributed Perl DocumeStatistics::Basic::Median(3)

NAME
       Statistics::Basic::Median - find	the median of a	list

SYNOPSIS
       Invoke it this way:

	   my $median =	median(1,2,3);

       Or this way:

	   my $v1  = vector(1,2,3);
	   my $med = median($v1);

       And then	either query the values	or print them like so:

	   print "The median of	$v1: $med\n";
	   my $mq = $med->query;
	   my $m0 = 0+$med;

       Create a	20 point "moving" median like so:

	   use Statistics::Basic qw(:all nofill);

	   my $sth = $dbh->prepare("select col1	from data where	something");
	   my $len = 20;
	   my $med = median()->set_size($len);

	   $sth->execute or die	$dbh->errstr;
	   $sth->bind_columns( my $val ) or die	$dbh->errstr;

	   while( $sth->fetch )	{
	       $med->insert( $val );
	       if( defined( $m = $med->query ) ) {
		   print "Median: $m\n";
	       }

	       # This would also work:
	       # print "Median:	$med\n"	if $med->query_filled;
	   }

METHODS
       new()
	   The constructor takes a single array	ref or a single
	   Statistics::Basic::Vector as	arguments.  It returns a
	   Statistics::Basic::Median object.

	   Note: normally you'd	use the	median() constructor, rather than
	   building these by hand using	"new()".

       _OVB::import()
	   This	module also inherits all the overloads and methods from
	   Statistics::Basic::_OneVectorBase.

OVERLOADS
       This object is overloaded.  It tries to return an appropriate string
       for the calculation or the value	of the computation in numeric context.

       In boolean context, this	object is always true (even when empty).
