Functional models for longitudinal data with covariate dependent smoothness

Mensah, David K.; Nott, David J.; Tan, Linda S. L.; Marshall, Lucy (University of Cape Coast, 2014)

This paper considers functional models for longitudinal data with subject and group specifc trends modelled using Gaussian processes. Fitting Gaussian process regression models is a computationally challenging task, and ...
A variational Bayes approach to a semiparametric regression using Gaussian process priors

Ong, Victor M. H.; Mensah, David K.; Nott, David J. (University of Cape Coast, 2016)

This paper presents a vibrational Bayes approach to a semi-parametric regression model that consists of parametric and nonparametric components. The assumed univariate nonparametric component is represented with a cosine ...
