glmmTMB Balances Speed and Flexibility Among Packages for Zero-inflated Generalized Linear Mixed Modeling

The R Journal, 2017
Count data can be analyzed using generalized linear mixed models when observations are correlated in ways that require random effects. However, count data are often zero-inflated, containing more zeros than would be expected from the typical error ...

On Linear Combinations of Harmonic Mappings Convex in the Horizontal Direction

Universal Journal of Mathematics and Applications
The process of creating univalent harmonic mappings which are not analytic is not simple or straightforward. One efficient method for constructing desired univalent harmonic maps is by taking the linear combination of two suitable harmonic maps. In this

Combination of linear classifiers using score function -- analysis of possible combination strategies

, 2019
In this work, we addressed the issue of combining linear classifiers using their score functions. The value of the scoring function depends on the distance from the decision boundary.

Laws of inertia in higher degree binary forms [PDF]

, 2009
We consider representations of real forms of even degree as a linear combination of powers of real linear forms, counting the number of positive and negative coefficients.

Efficient Multi-Dimensional Tensor Sparse Coding Using t-Linear Combination

AAAI Conference on Artificial Intelligence, 2018
In this paper, we propose two novel multi-dimensional tensor sparse coding (MDTSC) schemes using the t-linear combination. Based on the t-linear combination, the shifted versions of the bases are used for the data approximation, but without need to ...

Real-Time Quadruple-Frequency Cycle Slip Detection and Repair Algorithm Based on the Four Chosen Linear Combinations

IEEE Access, 2019
GNSS is now being speedily expanded to our daily life, but the positioning precision still can hardly meet the demands of many high-precision applications, such as approaching landing system on airports.

Expected Supremum of a Random Linear Combination of Shifted Kernels

, 2012
We address the expected supremum of a linear combination of shifts of the sinc kernel with random coefficients. When the coefficients are Gaussian, the expected supremum is of order \sqrt{\log n}, where n is the number of shifts.

Linear combinations of hypernormal operators

Rocky Mountain Journal of Mathematics, 1988
It is well known that if every operator in the linear span of two normal operators \(N_ 1\) and \(N_ 2\) is normal, then \(N_ 1\) and \(N_ 2\) commute. In this paper, the authors consider this question for hyponormal operators. They give an example of two noncommuting hyponormal operators such that their span consists entirely of hyponormal operators ...
