Generalized linear models with random effects are often used to explain the serial dependence of longitudinal categorical data. Marginalized random effects models (MREMs) permit likelihood-based estimations of marginal mean parameters and also explain the serial dependence of longitudinal data. In this paper, we extend the MREM to accommodate multivariate(More)
BACKGROUND Changes in microRNA (miRNA) expression patterns have been extensively characterized in several cancers, including human colon cancer. However, how these miRNAs and their putative mRNA targets contribute to the etiology of cancer is poorly understood. In this work, a bioinformatics computational approach with miRNA and mRNA expression data was(More)
PURPOSE To attempt to determine whether group audiologic rehabilitation (AR) content affected psychosocial outcomes. METHOD A randomized controlled trial with at least 17 participants per group was completed. The 3 treatment groups included a communication strategies training group, a communication strategies training plus psychosocial exercise group, and(More)
Recent sufficient dimension reduction methodologies in multivariate regression do not have direct application to a categorical predictor. For this, we define the multivariate central partial mean subspace and propose two methodologies to estimate it. The first method uses the ordinary least squares. Chi-squared distributed statistics for dimension tests are(More)
Sales of multivitamins have been growing rapidly and the concept of natural multivitamin, plant-based multivitamin, or both has been introduced in the market, leading consumers to anticipate additional health benefits from phytochemicals that accompany the vitamins. However, the lack of labeling requirements might lead to fraudulent claims. Therefore, the(More)
Many sufficient dimension reduction methodologies for univari-ate regression have been extended to multivariate regression. Sliced average variance estimation (SAVE) has the potential to recover more reductive information , and recent development enables us to test the dimension and predictor effects with distributions commonly used in the literature. The(More)
