Transformations of basic publication–citation matrices

Liang, Liming; Rousseau, Ronald - In: Journal of Informetrics 1 (2007) 3, pp. 249-255

Basic publication–citation matrices are used to calculate informetric indicators such as journal impact factors or R …-sequences. Transforming these publication–citation matrices clarifies the construction of other indicators. In this article, some … comparing informetric matrices before and after a transformation. …

A metric measure for weight matrices of variable lengths—with applications to clustering and classification of hidden Markov models

Yu, Yi-Kuo - In: Physica A: Statistical Mechanics and its Applications 375 (2007) 1, pp. 212-220

We construct a metric measure among weight matrices that are commonly used in non-interacting statistical physics … between two weight matrices is obtained via aligning the matrices and thus can be evaluated by dynamic programming. Capable of … weight matrices. The distance statistics among random motifs is also studied. We find that the average square distance and …

An adaptation of correspondence analysis for square tables

Greenacre, Michael - Department of Economics and Business, Universitat … - 1996

The application of correspondence analysis to square asymmetric tables is often unsuccessful because of the strong role played by the diagonal entries of the matrix, obscuring the data off the diagonal. A simple modification of the centering of the matrix, coupled with the corresponding change...
