Talk:Generalized method of moments

The statement that GMM is consistent for any positive semidefinite W is kind of strange. It should probably be any positively semidefinite W, where condition 2 applies or something like that. David Vonka (talk) 16:34, 8 January 2010 (UTC)

The statement "This article may be too technical for most readers to understand" may be irrelevant, may be redundant, and may be in need of deletion. — Preceding unsigned comment added by 88.128.80.4 (talk) 08:50, 24 April 2013 (UTC)

The link to Idempotence leads to a link for a different page - Projection (linear algebra) - although there is a link there that goes on to Idempotence — Preceding unsigned comment added by 131.111.176.55 (talk) 09:51, 15 April 2014 (UTC)
