Estimation in linear errors-in-variables models with unknown error distribution
Linh Nghiem, Michael Byrd, Cornelis Potgieter
Parameter estimation in linear errors-in-variables models typically requires that the measurement error distribution be known (or estimable from replicate data). A generalized meth…
Simulation-Selection-Extrapolation: Estimation in High-Dimensional Errors-in-Variables Models
Linh Nghiem, Cornelis Potgieter
This paper considers errors-in-variables models in a high-dimensional setting where the number of covariates can be much larger than the sample size, and there are only a small num…
Density Deconvolution for Generalized Skew-Symmetric Distributions
Cornelis J. Potgieter
This paper develops a density deconvolution estimator that assumes the density of interest is a member of the generalized skew-symmetric (GSS) family of distributions. Estimation o…
A Latent Trait Model for Multivariate Longitudinal Data With Two Sources of Measurement Error
Amy E. Nussbaum, Cornelis J. Potgieter, Michael Chmielewski
Personality traits are latent variables, and as such, are impossible to measure without the use of an assessment. Responses on the assessments can be influenced by both transient (…
An EM Algorithm for Estimating an Oral Reading Speed and Accuracy Model
Cornelis J. Potgieter, Akihito Kamata, Yusuf Kara
This study proposes a two-part model that includes components for reading accuracy and reading speed. The speed component is a log-normal factor model, for which speed data are mea…
