Hölder differentiability of self-conformal devil's staircases
(2014-03-01) - Journal article,
In this paper we consider the probability distribution function of a Gibbs measure supported on a self-conformal set given by an iterated function system (devil's staircase) applied to a compact subset of ℝ. We use ...
WinBUGS for population ecologists: Bayesian modeling using Markov Chain Monte Carlo methods.
(Springer Series: Environmental and Ecological Statistics, 2008) - Book item,
The computer package WinBUGS is introduced. We first give a brief introduction to Bayesian theory and its implementation using Markov chain Monte Carlo (MCMC) algorithms. We then present three case studies showing how ...
Models of random wildlife movement with an application to distance sampling
(2007) - Thesis,
In this paper we present three models of random wildlife movement: a one dimensional model of wildlife-observer encounters on roads, an analogous two dimensional model, and an further two-dimensional model that borrows ...
Retrospective power analysis
(1997) - Journal article,
Many papers have appeared in the recent biological literature encouraging us to incorporate statistical power analysis into our hypothesis testing protocol (Peterman 1990; Fairweather 1991; Muller & Benignus 1992; Taylor ...
Distance software: design and analysis of distance sampling surveys for estimating population size
(2010) - Journal article,
1. Distance sampling is a widely used technique for estimating the size or density of biological populations. Many distance sampling designs and most analyses use the software Distance. 2. We briefly review distance sampling ...
A unified framework for modelling wildlife population dynamics
(2005) - Journal article,
This paper proposes a unified framework for defining and fitting stochastic, discrete-time, discrete-stage population dynamics models. The biological system is described by a state–space model, where the true but unknown ...
Density estimation and time trend analysis of large herbivores in Nagarhole, India
(2005) - Thesis,
Density estimates for six large herbivore species were obtained through analysis of line transect data from Nagarhole National Park, south-western India, collected between 1989 and 2000. These species were Chital (Axis ...
Dimensions of sets which uniformly avoid arithmetic progressions
(2017-11-02) - Journal article,
We provide estimates for the dimensions of sets in ℝ which uniformly avoid finite arithmetic progressions (APs). More precisely, we say F uniformly avoids APs of length k≥3 if there is an ϵ>0 such that one cannot find an ...
Evaluating the effect of measurement error in pairs of 3D bearings in point transect sampling estimates of density
(University of St Andrews, 2018-03-27) - Report,
Incorporating animal movement into distance sampling
(2017-09-08) - Journal article,
Distance sampling is a popular statistical method to estimate the density of wild animal populations. Conventional distance sampling represents animals as fixed points in space that are detected with an unknown probability ...
