Reconceptualizing Survey Representativeness for Evaluating and Using Nonprobability Samples [PDF]

open access: bronzeSurvey Practice, 2013
A question in recent times has been the quality of surveys using nonprobability samples. This paper approaches measurement accuracy by reconceptualizing representativeness. This approach can be used for all samples, probability or not. Current survey designs aim for representative samples with the implicit assumptions that representativeness belongs to

Online Nonprobability Samples

open access: yesAnnual Review of Sociology
Online nonprobability samples provide social scientists with opportunities to conduct surveys and experiments on large, diverse samples at modest prices. Researchers may find bewildering the options offered by the many commercial entities that provide research participants, and our review seeks to orient researchers to key issues about their use.

Integration of Nonprobability and Probability Samples via Survey Weights

open access: diamondInternational 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.

Comparing Alternatives for Estimation from Nonprobability Samples [PDF]

open access: bronzeJournal of Survey Statistics and Methodology, 2019
AbstractThree approaches to estimation from nonprobability samples are quasi-randomization, superpopulation modeling, and doubly robust estimation. In the first, the sample is treated as if it were obtained via a probability mechanism, but unlike in probability sampling, that mechanism is unknown.

Data integration with nonprobability sample: Semiparametric model‐assisted approach [PDF]

open access: bronzeScandinavian Journal of Statistics
Abstract This paper introduces a novel semiparametric model‐assisted estimation method that integrates data from both probability and nonprobability samples, thereby facilitating robust and efficient inferences regarding finite population parameters.

occAssess: An R package for assessing potential biases in species occurrence data

open access: yesEcology and Evolution, 2021
Species occurrence records from a variety of sources are increasingly aggregated into heterogeneous databases and made available to ecologists for immediate analytical use. However, these data are typically biased, i.e.

Comparing Probability-Based Surveys and Nonprobability Online Panel Surveys in Australia: A Total Survey Error Perspective

open access: yesSurvey Research Methods, 2022
In this paper we report the findings from our study which was undertaken to learn if the findings of Chang et al. (2009), Yeager et al. (2011), Erens et al. (2014), MacInnis et al. (2018) and Cornesse et al. (2020) would be replicated in Australia.
