In this dissertation, we explore the properties of correlation structure for spatio-temporalpoint processes and a quantitative spatial process. Spatio-temporal pointprocesses are often assumed to be separable; we propose a formal approach for testingwhether a particular data set is indeed...

We also assume thatthe clustering membership is a realization from a Markov random field. Under … clustering algorithm under a series of settings: small number of time points, high noise level and varying dependence structures …

Spatial or spatio-temporal data are frequently encountered in many scientific disciplines. One major challenge in modeling these processes is the high dimensionality of such data; that is, the number of observations is usually enormous. The first part of the dissertation proposes an efficient...

Spatial and temporal issues are often important concepts within agricultural economics research. Understanding these issues and developing models that incorporate spatio-temporal frameworks can lead to more accuracy in answering important economic questions. This thesis uses the spatio-temporal...

Using estimation of demand for the George Washington/Jefferson NationalForest as a case study, it is shown that in a stratified/clustered on-sitesample, latent heterogeneity needs to be accounted for twice: first to accountfor dispersion in the data caused by unobservability of the process that...
