Robust score matching for compositional data
Janice L. Scealy, Kassel L. Hingee, John T. Kent +1
The restricted polynomially-tilted pairwise interaction (RPPI) distribution gives a flexible model for compositional data. It is particularly well-suited to situations where some o…

Estimation and Testing for Covariance-Spectral Spatial-Temporal Models
A. M. Mosammam, J. T. Kent
In this paper we explore a covariance spectral modelling strategy for spatial-temporal processes which involves a spectral approach for time but a covariance approach for space.It…
