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 weProstatism 发表于 2025-3-27 17:10:21
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 testsallergen 发表于 2025-3-27 20:13:54

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配偶 发表于 2025-3-28 09:24:21
