Integration of Nonprobability and Probability Samples via Survey Weights

open access: yesInternational Journal of Statistics and Probability, 2021
Probability sample encounters the problems of increasing cost and nonresponse. The cost has rapidly been increasing in executing a large probability sample survey, and, for some surveys, response rate can be below the 10 percent level. Therefore, statisticians seek some alternative methods.

Propensity score adjustment using machine learning classification algorithms to control selection bias in online surveys.

open access: yesPLoS ONE, 2020
Modern survey methods may be subject to non-observable bias, from various sources. Among online surveys, for example, selection bias is prevalent, due to the sampling mechanism commonly used, whereby participants self-select from a subgroup whose ...

Enhancing estimation methods for integrating probability and nonprobability survey samples with machine‐learning techniques. An application to a Survey on the impact of the COVID‐19 pandemic in Spain

open access: yesBiometrical journal. Biometrische Zeitschrift, 2022
Web surveys have replaced Face‐to‐Face and computer assisted telephone interviewing (CATI) as the main mode of data collection in most countries. This trend was reinforced as a consequence of COVID‐19 pandemic‐related restrictions.

Online Surveys in Latin America

open access: yesPS: Political Science & Politics, 2023
Online surveys of public opinion are less expensive and faster to administer than other surveys. However, nonprobability online samples diverge from the gold standard of probabilistic sampling.

Supplementing Small Probability Samples with Nonprobability Samples: A Bayesian Approach

open access: yesJournal of Official Statistics, 2019
Carefully designed probability-based sample surveys can be prohibitively expensive to conduct. As such, many survey organizations have shifted away from using expensive probability samples in favor of less expensive but possibly less accurate ...

The effects of survey mode and sampling in Belgian election studies: a comparison of a national probability face-to-face survey and a nonprobability Internet survey

open access: yesActa Politica, 2020
© 2018, Springer Nature Limited. National probability election surveys are more and more abandoned. Decreasing response rates and the escalating costs of face-to-face and telephone interviews have strengthened election scholars’ reliance on ...

A Process for Decomposing Total Survey Error in Probability and Nonprobability Surveys: A Case Study Comparing Health Statistics in US Internet Panels

open access: yesJournal of Survey Statistics and Methodology, 2019
Abstract As survey methods evolve, researchers require a comprehensive understanding of the error sources in their data. Comparative studies, which assess differences between the estimates from emerging survey methods and those from traditional surveys, are a popular tool for evaluating total error; however, they do not provide insight ...
