David Merten had just reported problem with OS X Lion and
stats_kmeans.plas well. Unfortunate I don't have a mac. For a start
can you do me a favor
and add this line between 172 and 173
172> my %m = $data->kmeans({NCLUS=>2, NTRY=>10, V=>0});
print $m{ms}->sumover;
173> return sum( $m{ms}->sumover - pdl qw( 1.5 1.9166667 1.9166667 ) );
Best,
Maggie
