Karl, yes it is as German as your name.Value means "Wert" and eigenvalue means "Eigenwert" and I guess it goes back to Carl Friedrich Gauss who provided us with many math concepts,i.e. matrix algebra among many others. In Germany we honor him very much.His portrait is on our 10 DM bill,with

Suppose we assume the behavior _is_ completely random, such as the stimulus comes from outside the subject. We define the behavior as present if it is observed during any one second period. We assume/assert that p(event) in 7 hours = 1 (as stated). then p(event) in any 15 minute period woul

Hi I have been conducting goodness of fit tests using A-D tests and one thing i forgot to do beforehand was to find out if A-D tables of critical values exist. I have read one book from D'Agostino and Stephens(1986) they outline distribution specific A-D test critical values which rely on formula

A square matrix can be used to transform a vector in length, direction, or both.  For example, a vector with two elements can be post-multiplied by a 2x2 matrix to generate a new two-element vector.  If the vector is unchanged in direction, the vector is an 'eigen vector' for the matrix.  Li

Your national pride does you credit. Gauss was one of the greats, and he may have used "eigenvalue" or its equivalent, but I don't know for sure -- do you really, or are you guessing? It is hard to be certain with Gauss, because of his brilliance, but I doubt that he used the general linear model

Ich Bein Ein Eigenvector, Victor

2001-01-20 Thread jeff rasmussen
Eigen means self. The terms eigenvector, eigenvalues, etc come from one method of generating these values, which is that they are self-reproducing; that is, they will stabilize on the correct value after a series of iterations. I wish I could recall the method that you use to start the iterations
