*Abstract*: In this talk, I will introduce a multi-resolution spatial
method, which uses a special class of basis functions extracted from
thin-plate splines. The functions are ordered in terms of their degrees of
smoothness with higher-order functions corresponding to larger-scale
features and lower-order ones corresponding to smaller-scale details,
leading to a parsimonious representation of a spatial process with the
number of basis functions playing the role of spatial resolution. Some
applications of this method will be introduced, including spatial
prediction of fine particulate matter (PM2.5) based on data from small
internet-of-things sensing devices, called AirBoxes, and independence test
between two spatial random fields using a dimension-reduced canonical
correlation analysis method.
