Modeling complex interactions involving multiple response variables is a difficult problem. Response variables are often correlated with each other, have causal relationships and are influenced by factor main effects, interactions and covariates. When analyzing these types of da…

The performance of several widely-known methods for analyzing data utilizing nonlinear mixed effects models are evaluated via simulation in two settings. Each setting is a hierarchical mixed effects model in which repeated observations on a subject are modeled by subject-specifi…

Difficulties in speech production are often marked by disfluency; fillers, hesitations, prolongations, repetitions and repairs. In recent years a body of work has emerged that demonstrates that listeners are sensitive to disfluency, and that this affects their expectations for u…
