Explicit minimisation of a convex quadratic under a general quadratic constraint: a global, analytic approach
Casper Albers, Frank Critchley, John Gower
A novel approach is introduced to a very widely occurring problem, providing a complete, explicit resolution of it: minimisation of a convex quadratic under a general quadratic, eq…
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…
