To replace or not to replace in finite population sampling

open access: yes, 2016
We revisit the classical result in finite population sampling which states that in equally-likely "simple" random sampling the sample mean is more reliable when we do not replace after each draw. In this paper we investigate if and when the same is true for samples where it may no longer be true that each member of the population has an equal chance of

A Modified Forced Randomized Response Model

open access: yesJournal of Nigerian Society of Physical Sciences, 2020
In this paper, we proposed a new Randomized Response Model (RRM) that estimate proportion of people in a population (P) belonging to a sensitive group (S) under study.

On death processes and urn models [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We use death processes and embeddings into continuous time in order to analyze several urn models with a diminishing content. In particular we discuss generalizations of the pill's problem, originally introduced by Knuth and McCarthy, and generalizations

A Probability Proportional to Size Estimation of a Rare Sensitive Attribute Using a Partial Randomized Response Model with Poisson Distribution

open access: yesMathematics
In this paper, we suggest using a partial randomized response model using Poisson distribution to efficiently estimate a rare sensitive attribute by applying the probability proportional to size (PPS) sampling method when the population is composed of ...

Risk factor analysis of device-related infections: value of re-sampling method on the real-world imbalanced dataset

open access: yesBMC Medical Informatics and Decision Making, 2019
Background The incidence of cardiac implantable electronic device infection (CIEDI) is low and usually belongs to the typical imbalanced dataset. We sought to describe our experience on the management of the imbalanced CIEDI dataset.
