Strong Laws for Weighted Sums of Negative Dependent Random Variables [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2005
In this paper, we discuss strong laws for weighted sums of pairwise negatively dependent random variables. The results on i.i.d case of Soo Hak Sung [9] are generalized and extended.

On the number of weighted zero-sum subsequences

open access: yesPeriodica Mathematica Hungarica, 2023
Let $G$ be a finite additive abelian group with exponent $d^kn, d,n>1,$ and $k$ a positive integer. For $S$ a sequence over $G$ and $A=\{1,2,\ldots,d^kn-1\}\setminus\{d^kn/d^i:i\in[1,k]\}, $ we investigate the lower bound of the number $N_{A,0}(S)$, which denotes the number of $A$-weighted zero-sum subsequences of $S.$ In particular, we prove that ...

Ranking by weighted sum [PDF]

open access: yesEconomic Theory, 2020
AbstractWhen choosing an alternative that has multiple attributes, it is common to form a weighted sum ranking. In this paper, we provide an axiomatic analysis of the weighted sum criterion using a general choice framework. We show that a preference order has aweakweighted sum representation if it satisfies three basic axioms: Monotonicity, Translation

On complete moment convergence for weighted sums of negatively superadditive dependent random variables [PDF]

open access: yes, 2020
summary:In this work, the complete moment convergence and complete convergence for weighted sums of negatively superadditive dependent (NSD) random variables are studied, and some equivalent conditions of these strong convergences are established.

Estimating Sum by Weighted Sampling [PDF]

open access: yes, 2007
We study the classic problem of estimating the sum of n variables. The traditional uniform sampling approach requires a linear number of samples to provide any non-trivial guarantees on the estimated sum. In this paper we consider various sampling methods besides uniform sampling, in particular sampling a variable with probability proportional to its ...

Sums of Gauss sums and weights of irreducible codes

open access: yesFinite Fields and Their Applications, 2005
This paper develops a matrix approach to compute a certain sum of Gauss sums that arises in the study of weights of irreducible codes. The authors have further derived a lower bound on the minimum weight of certain irreducible codes. Though the studies made have been restricted to binary codes, however, the methods of this paper applies to codes of odd

Three conjectures about character sums [PDF]

open access: yes, 2023
We establish that three well-known and rather different looking conjectures about Dirichlet characters and their (weighted) sums, (concerning the Pólya–Vinogradov theorem for maximal character sums, the maximal admissible range in Burgess’ estimate for ...
