Book excerpt: Modeling and analysis of multivariate geo-referenced data are of great interest in disciplines such as ecology, agriculture, and the environmental sciences. However, the development of statistical methods for such data has been rather limited. This dissertation consisting of three papers discusses latent variable analysis of multivariate spatial data. The first paper introduces the generalized shifted-factor model and its use in modeling a wide variety of spatial dependence characteristics. The model incorporates potential lagged dependencies between factors and observed variables, representing asymmetric spatial, cross-variable dependencies observed in practice. Identification of such lagged dependencies or shifted factors is discussed, and tools for practical implementation of the approach are given. Methods for parameter estimation, inference, and latent variable prediction are described for researchers in applied sciences.
