NAMEStatistics::Basic::Median - find the median of a listSYNOPSISInvoke 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
