Generalized Score Matching for Regression
Jiazhen Xu, Janice L. Scealy, Andrew T. A. Wood +1
Many probabilistic models that have an intractable normalizing constant may be extended to contain covariates. Since the evaluation of the exact likelihood is difficult or even imp…
Gaussian asymptotic limits for the -transformation in the analysis of compositional data
Yannis Pantazis, Michail Tsagris, Andrew T. A. Wood
Compositional data consists of vectors of proportions whose components sum to 1. Such vectors lie in the standard simplex, which is a manifold with boundary. One issue that has bee…
Saddlepoint approximation for moment generating functions of truncated random variables
Ronald W. Butler, Andrew T. A. Wood
We consider the problem of approximating the moment generating function (MGF) of a truncated random variable in terms of the MGF of the underlying (i.e., untruncated) random variab…
Estimation of fractal dimension for a class of Non-Gaussian stationary processes and fields
Grace Chan, Andrew T. A. Wood
We present the asymptotic distribution theory for a class of increment-based estimators of the fractal dimension of a random field of the form g{X(t)}, where g:R\to R is an unknown…
