One kind hybrid character sums and their upper bound estimates [PDF]
Journal of Inequalities and Applications, 2018 The main purpose of this paper is applying the analysis method, the properties of Lucas polynomials and Gauss sums to study the estimation problems of some kind hybrid character sums. In the end, we obtain several sharp upper bound estimates for them. As

An upper bound for functions of estimators in high dimensions [PDF]
Econometric Reviews, 2020 We provide an upper bound as a random variable for the functions of estimators in high dimensions. This upper bound may help establish the rate of convergence of functions in high dimensions. The upper bound random variable may converge faster, slower, or at the same rate as estimators depending on the behavior of the partial derivative of the function.

Where forest may not return in the western United States
Ecological Indicators, 2023 Droughts that are hotter, more frequent, and last longer; pest outbreaks that are more extensive and more common; and fires that are more frequent, more extensive, and perhaps more severe have raised concern that forests in the western United States may ...

Estimation Method for Upper Bound of General Pattern Index Based on Modified BPSO [PDF]
Jisuanji gongcheng, 2018 A general pattern index upper bound estimation method based on modified Binary Particle Swarm Optimization (BPSO) algorithm is proposed to estimate the boundary value estimation problem in constrained frequent pattern mining.According to the ...

An upper-bound estimate for the accuracy of glacier volume–area scaling [PDF]
The Cryosphere, 2013 Volume–area scaling is the most popular method for estimating the ice volume of large glacier samples. Here, a series of resampling experiments based on different sets of synthetic data is presented in order to derive an upper-bound estimate (i.e.

An Optimal Estimate for the Anisotropic Logarithmic Potential
Mathematics, 2022 This paper introduces the new annulus body to establish the optimal lower bound for the anisotropic logarithmic potential as the complement to the theory of its upper bound estimate which has already been investigated.

Lower and upper bound estimates of inequality of opportunity for emerging economies [PDF]
Social Choice and Welfare, 2021 AbstractEquality of opportunity is an important normative ideal of distributive justice. In spite of its wide acceptance and economic relevance, standard estimation approaches suffer from data limitations that can lead to both downward and upward biased estimates of inequality of opportunity.

Variational Inference via Rényi Bound Optimization and Multiple-Source Adaptation
Entropy, 2023 Variational inference provides a way to approximate probability densities through optimization. It does so by optimizing an upper or a lower bound of the likelihood of the observed data (the evidence).
