NAME

SYNOPSIS

    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

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