the puzzle in the covariance

From: Ye Hongbo Date: December 13, 2009 technical
Dear professor: THE off diagnoal: Sometimes we make the OMEGA syntax as follows:$omega 0.1 0.1,but $omega blokc (2) 0.1 0.01 0.1 at another occasion.As we know,the only difference is whether the off diagonal estimate be used.So is there any specila condition about the existence of the W21,or some another W square like that? Thank you !!! -- 工作和生活,都要开心的过. 你好,叶红波在此送上真挚的祝福.祝你开心, 叶红波
