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

Survey 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.

On the Use of Gradient Boosting Methods to Improve the Estimation with Data Obtained with Self-Selection Procedures

Mathematics, 2021
In the last years, web surveys have established themselves as one of the main methods in empirical research. However, the effect of coverage and selection bias in such surveys has undercut their utility for statistical inference in finite populations. To

Methods to Counter Self-Selection Bias in Estimations of the Distribution Function and Quantiles

Mathematics, 2022
Many surveys are performed using non-probability methods such as web surveys, social networks surveys, or opt-in panels. The estimates made from these data sources are usually biased and must be adjusted to make them representative of the target ...

Estimating General Parameters from Non-Probability Surveys Using Propensity Score Adjustment

Mathematics, 2020
This study introduces a general framework on inference for a general parameter using nonprobability survey data when a probability sample with auxiliary variables, common to both samples, is available.

Inference from Non-Probability Surveys with Statistical Matching and Propensity Score Adjustment Using Modern Prediction Techniques

Mathematics, 2020
Online surveys are increasingly common in social and health studies, as they provide fast and inexpensive results in comparison to traditional ones. However, these surveys often work with biased samples, as the data collection is often non-probabilistic ...

Harmonizing Single-Question Instruments for Latent Constructs With Equating Using Political Interest as an Example.

Survey Research Methods, 2022
Many latent constructs in the social sciences, such as political interest, are measured with single-question instruments. Furthermore, survey programs often differ in the wording and response format of those instruments.

The Utility of an Online Convenience Panel for Reaching Rare and Dispersed Populations. [PDF]

PLoS ONE, 2015
Gaps in data collection systems, as well as challenges associated with gathering data from rare and dispersed populations, render current health surveillance systems inadequate to identify and monitor efforts to reduce health disparities.
