Stochastic integration using random point processes

Creator:: Lipman, Harvey Bennett
Resource Type:: Dissertation

Estimation of the order of an autoregressive time series : a Bayesian approach

Creator:: Robb, Loretta J.
Abstract:: Finite order autoregressive models for time series are often used for prediction and other inferences. Given the order of the model, the parameters of the models can be estimated by least squares, maximum likelihood, or the Yule-Walker method. The basic problem is estimating the order of the model. A number...

Adaptive sampling of spatial point processes

Creator:: Thompson, Steven Kirk
Abstract:: Adaptive sampling designs are those in which observations made during a survey may be taken into account when selecting the sites for further observations. Increases in survey precision may be achieved through adaptive procedures. The most efficient designs incorporate flexible sample size along with sequential selection of sites. In surveys...

A new estimator of effective area surveyed in wildlife studies

Creator:: Wildman, Valerie Jean
Abstract:: A new estimator of effective area surveyed is proposed for use in estimating population sizes or densities. The estimator is based on the cumulative distribution function for the observed detection areas and can be used with the data arising from either a line transect or a variable circular plot survey....

Estimation of the feedback parameters in a closed-loop system : a geophysical problem

Creator:: Cid, Luis Serrano
Abstract:: The presence of feedback in an inputoutput system associated with an oceanographic phenomenon is determined. A testing procedure to determine the presence of feedback is given. The ordinary transfer function model is determined not to be appropriate in modeling the system. The two and three stage least squares methods are...

Factors affecting bird counts and their influence on density estimates

Creator:: McCracken, Marti L.
Abstract:: Variable area surveys are used in large geographic regions to estimate the density of birds distributed over a region. If some birds go undetected, a measure of the effective area surveyed, the amount of area occupied by the birds detected, is needed. The effective area surveyed is determined by observational,...

Uses of Bayesian posterior modes in solving complex estimation problems in statistics

Creator:: Lin, Lie-fen
Abstract:: In Bayesian analysis, means are commonly used to summarize Bayesian posterior distributions. Problems with a large number of parameters often require numerical integrations over many dimensions to obtain means. In this dissertation, posterior modes with respect to appropriate measures are used to summarize Bayesian posterior distributions, using the Newton-Raphson method...

The use of logistic regression for developing habitat association models

Creator:: Sjamsoe'oed, Roza
Abstract:: Quantitative habitat models of wildlife-habitat relationships are developed to formalize our current understanding about an ecological system. A habitat association model is one of these models that is useful for answering questions about how the habitat is occupied, how much growth habitat is required by the animal, or how the...

Diagnostics for the evaluation of spatial linear models

Creator:: Thompson, Caryn M. (Caryn Marie)
Abstract:: Geostatistical linear interpolation procedures such as kriging require knowledge of the covariance structure of the spatial process under investigation. In practice, the covariance of the process is unknown, and must be estimated from the available data. As the quality of the resulting predictions, and associated mean square prediction errors, depends...

Persistence and heterogeneity in habitat selection studies

Creator:: Usner, Dale Wesley
Abstract:: Recently the independent multinomial selections model (IMS) with the multinomial logit link has been suggested as an analysis tool for radio-telemetry habitat selection data. This model assumes independence between animals, independence between sightings within an animal, and identical multinomial habitat selection probabilities for all animals. We propose two generalizations to...
