Abstract:

Many investigations in the environmental and biological sciences encounter data that is inherently multivariate, exhibits complex structure, and has various forms of dependence, in particular spatial dependence. A strategy is presented for multiple-response regression problems that uses the connection between spatial models (universal kriging) and thin-plate splines to model nonlinear relationships between explanatory and response variables via a type of smoothing. Furthermore, this strategy is reminiscent of semiparametric mixed models. In addition, spatial dependence can also be easily be incorporated. The methodology will be demonstrated using several examples, including the modeling of soil water profiles (pedotransfer functions) for use with crop models to examine sources of variation in crop yields and the modeling of skin cancer rates and climate variables.
