Modelling tree survival for investigating climate change effects
Nicole N. Augustin, Axel Albrecht, Karim Anaya-Izquierdo +4
Using German forest health monitoring data we investigate the main drivers leading to tree mortality and the association between defoliation and mortality; in particular (a) whethe…
Approximation and sampling of multivariate probability distributions in the tensor train decomposition
Sergey Dolgov, Karim Anaya-Izquierdo, Colin Fox +1
General multivariate distributions are notoriously expensive to sample from, particularly the high-dimensional posterior distributions in PDE-constrained inverse problems. This pap…
Logistic regression geometry
Karim Anaya-Izquierdo, Frank Critchley, Paul Marriott
This paper looks at effects, due to the boundary, on inference in logistic regression. It shows that first -- and, indeed, higher -- order asymptotic results are not uniform across…
Computational information geometry: theory and practice
Karim Anaya-Izquierdo, Frank Critchley, Paul Marriott +1
This paper lays the foundations for a unified framework for numerically and computationally applying methods drawn from a range of currently distinct geometrical approaches to stat…
Orthogonal simple component analysis: A new, exploratory approach
Karim Anaya-Izquierdo, Frank Critchley, Karen Vines
Combining principles with pragmatism, a new approach and accompanying algorithm are presented to a longstanding problem in applied statistics: the interpretation of principal compo…
Local mixture models of exponential families
Karim Anaya-Izquierdo, Paul Marriott
Exponential families are the workhorses of parametric modelling theory. One reason for their popularity is their associated inference theory, which is very clean, both from a theor…
