about expression of eigenvalue decomposition: when we write A=VDV', the D, eigenvalues, could be explained as a scalar; however, it actually is a set of numbers that forms a diagonal matrix. As AV=VD, and VD is not DV, writing the equation as AV=DV is simply wrong, isn't it? Csa slb (talk) 05:17, 23 January 2015 (UTC)

Hello, I'm DoubleGrazing, and welcome to Wikipedia. I appreciate your contributions, but in one or more sections of Draft:Statistical properties of earthquake data, it appears that you added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you. DoubleGrazing (talk) 05:35, 24 April 2026 (UTC)
