Trace of exponential matrix
SpletAs a consequence, we obtain that if the horizontal and vertical pairs of an exponential Riordan matrix are identical then the matrix is an involution. In addition, this concept can be applied to obtain the determinants of the production matrix and some conditions for the d-orthogonality of the Sheffer polynomial sequences. (C) 2024 Elsevier Inc. Splet24. jun. 2003 · The eigenvalues of a projection matrix are either 0 or 1, and the number of non-zero eigenvalues equals its rank; hence the trace of P is m and the expected value of p ii is m/N. The factor by which the hat matrix diagonal estimate must exceed the expected value to be considered a leverage point is not well defined, but statistical lore ...
