Plumbing the Depths of the Shallow End: Exploring Persistent Homology Using Small Data
… software R on controlled datasets. A kernel density estimate diagram presents the results. We showcase applying TDA to an external, uncontrolled dataset. The limits on memory allowed us to process no more than four columns of data at a time. To more thoroughly explore the dataset, we …

Essays in econometrics
… an example, fixed eff ects panel data model is estimated using a pseudo-panel of cluster centers. Chapters 2 and 3 extend univariate kernel methods to the estimation of time-varying distributions and densities subject to moment constraints. Chapter 2 proposes a weighted kernel density estimator …

How well do buffer circles capture the ranging behaviours of territorial raptors?
… whose dimensions were based on the species' 95% Kernel Density Estimate (KDE) did relatively well at capturing the proportion of individual GPS fixes, but did less well at capturing the KDE area from tracked birds. For buffer circles to capture 95% of the home range polygons (95% KDE) they would …

Parametric, Non-Parametric And Statistical Modeling Of Stony Coral Reef Data
… coral cover proportions and we obtain better estimates of the statistical properties of stony coral cover proportions. Furthermore, we improve present procedures in constructing confidence intervals of the true median and mean for the underlying probability distribution. In chapter three, we …

Resource Selection, Home Range and Habitat Associations of the Southern Fox Squirrel (<i>Sciurus niger niger</i>) in the Piedmont and Coastal Plain of Virginia
… area and Piney Grove Complex using 95% and 50% kernel density estimate. I found an average male home range 173.49 ha (SE = 25.73, N = 2) and 40.62 ha (SE = 5.87, N = 2) and an average female home range of 28.51 ha (SE = 0.49, N = 2) and 4.71 ha (SE = 0.34, N = 2). I then identified the second …

Goal-oriented inference : theoretical foundations and application to carbon capture and storage
… or specification of a prior probability density in Bayesian statistical formulations to resolve the ill-posedness manifested in the many possible parameters giving rise to the same observed data. Critically, the final prediction requirements are not considered in the inference process. …

Plasticity and partitioning of foraging behaviour among and within sympatric Pygocelis penguin populations
… a repeatability index. I used an autocorrelated kernel density estimate approach to quantify space use and overlap between species as breeding transitioned from incubation to brood and crèche. Sites greatly influenced both species' foraging behaviours, with the Kopaitic Island environment being a …
