Local Sensitivity of Failure Probability through Polynomial Regression and Importance Sampling

open access: yesMathematics, 2023
Evaluating the failure probability of a system is essential in order to assess its reliability. This probability may significantly depend on deterministic parameters such as distribution parameters or design parameters.

Bayesian probability updates using sampling/importance resampling: Applications in nuclear theory

open access: yesFrontiers in Physics, 2022
We review an established Bayesian sampling method called sampling/importance resampling and highlight situations in nuclear theory when it can be particularly useful.

EDITORIAL – A REVIEW OF THE METHODOLOGICAL MISCONCEPTIONS AND GUIDELINES RELATED TO THE APPLICATION OF STRUCTURAL EQUATION MODELING: A MALAYSIAN SCENARIO [PDF]

open access: yesJournal of Applied Structural Equation Modeling, 2017
Although structural equation modeling (SEM) is a powerful statistical technique, understanding its methodological assumptions before data analyses is essential to attaining more robust results.

Essay: Sunday shopping - The case of three surveys

open access: yesSurvey Research Methods, 2015
There is a growing discussion about the use of non-probability sampling in survey research. Probability sampling is the preferred method of sample selection, but practical problems like reduced data collection budgets, increasing nonresponse rates, and ...

On accuracy of PDF divergence estimators and their applicability to representative data sampling [PDF]

open access: yes, 2011
Generalisation error estimation is an important issue in machine learning. Cross-validation traditionally used for this purpose requires building multiple models and repeating the whole procedure many times in order to produce reliable error estimates ...

Deep Hash Remote Sensing Image Retrieval with Hard Probability Sampling

open access: yesRemote Sensing, 2020
As satellite observation technology improves, the number of remote sensing images significantly and rapidly increases. Therefore, a growing number of studies are focusing on remote sensing image retrieval. However, having a large number of remote sensing

Probabilistic sampling strategy as a means of improving quality of price indices

open access: yesCroatian Review of Economic, Business and Social Statistics, 2018
In spite of theoretical inferiority, a large majority of statistical institutes use non-probabilistic sampling techniques in price surveys. The main disadvantage of non-probabilistic sample design is that the risk of biased results is increased ...

Against All Odds: On the Robustness of Probability Samples Against Decreases in Response Rates

open access: yesSurvey Research Methods
Responses rates in surveys with probability samples have decreased in the last decades, but has this decrease caused a decline in sample quality? Our paper addresses this question with an analysis of methodological data describing 776 surveys from four ...

Empirical likelihood inference for the Rao-Hartley-Cochran sampling design

open access: yes, 2016
The Hartley-Rao-Cochran sampling design is an unequal probability sampling design which can be used to select samples from finite populations. We propose to adjust the empirical likelihood approach for the Hartley-Rao-Cochran sampling design.
