It's a different title, anyway. It was never really established to be a different topic. — Arthur Rubin(talk) 07:11, 21 October 2010 (UTC)
If the topic covered by Numerical methods for linear least squares and Ordinary least squares are the same topic, the renaming it was wrong. If this title represents the same topic as Numerical methods for linear least squares, then this would still redirect to Numerical methods for linear least squares. As both pages exist, then they must be different topics. Note that a subtopic is a different topic from the topic it is a subtopic of (a subset is different from its superset, except in trivial cases, therefore they are different sets, if it is a trivial case, renaming the article was foolish; Wikipedia does not keep two articles about the exact same topic around, only supersets and subsets.). 76.66.198.128 (talk) 13:24, 21 October 2010 (UTC)
Wrong. The consensus at the time as that the articles and topics were on the same topic; however the action taken did not reflect consensus. As you probably know, even if you have an account, renames do not appear on your watch list, so it's probable that no one noticed the rename until recently. — Arthur Rubin(talk) 14:55, 21 October 2010 (UTC)
