Benford Behavior in Stick Fragmentation Problems

open access: yesStats
Benford’s law states that in many real-world datasets, the probability that the leading digit is d equals log10((d+1)/d) for all 1≤d≤9. We call this weak Benford behavior.

The Efficiency of Missing at Random Planned Missing Designs

open access: yesMathematics
Planned Missing Designs (PMDs) allow for different sets or patterns of variables to be collected from sample units. While the typical motivation for PMDs is to manage respondent burden, they can also reduce data collection costs and provide flexibility ...

Exact Tests for Two-Way Contingency Tables with Structural Zeros

open access: yesJournal of Statistical Software, 2008
Fisher's exact test, named for Sir Ronald Aylmer Fisher, tests contingency tables for homogeneity of proportion. This paper discusses a generalization of Fisher's exact test for the case where some of the table entries are constrained to be zero.

Another approach to the evaluation of a certain multivariate compound distribution

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
In this work, we consider the multivariate aggregate model introduced in [11], model that takes into account the case when different types of claims affect in the same time an insurance portfolio under some specific assumptions related to the number of ...

On the Exchangeable Multinomial Distribution [PDF]

open access: yes, 2010
We derive an expression of the joint distribution of exchangeable multinomial random variables. In the literature this problem has mainly been addressed by the use of an extension of de Finetti\u27s theorem for binary data.

Bayesian sequential estimation of the proportion of damage in maize seeds

open access: yesScientia Agricola
Sampling is an essential step in estimating a parameter: thus, cost and time associated to this step should be minimized. Sequential sampling is characterized by using samples of variable sizes given as a function of observations, and sequential sampling

Constructing two-sided simultaneous confidence intervals for multinomial proportions for small counts in a large number of cells [PDF]

open access: yes
Confidence intervals for multinomial proportions are often constructed using large-sample methods that rely on expected cell counts of 5 or greater. In situations that give rise to a large number of categories, the cell counts may not be of adequate size

Characterizations of multinomial distributions based on conditional distributions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
Several characterizations of the joint multinomial distribution of two discrete random vectors are derived assuming conditional multinomial distributions.
