Developments in science and technology over the last two decades has motivated the study of complex data objects. In this article, we consider the topological properties of a population of tree-structured objects. Our interest centers on modeling the relationship between a tree-structured...

In particular, we consider a geostatistical model with additive components, where the form of the covariance function of the spatial random error is not prespecified...</p>
