A Notion of Positive Definiteness for Arithmetical Functions,atrices associated with these functions. In the present article we consider how to define a similar positive definiteness property for arithmetical functions, whose domain is not the set of real numbers but merely the set of positive integers. After finding a suitable definition for this concept we

Some Issues in Generalized Linear Modeling,phasis on categorical data, we summarize (1) bias that can occur in using ordinary linear models with ordinal response variables, (2) a new proposal about simple ways to interpret effects in generalized linear models that use nonlinear link functions, (3) problems with using Wald significance tests

Covariance Matrix Regularization for Banded Toeplitz Structure via Frobenius-Norm Discrepancy,ery difficult particularly for high-dimensional data. In this article, we propose a regularization method for finding a possible banded Toeplitz structure for a given covariance matrix . (e.g., sample covariance matrix), which is usually an estimator of the unknown population covariance matrix .. We
