Methods for capturing images in three dimensions are now widely available, with stereo-photogrammetry and laser scanning being two common approaches. In anatomical studies, a number of landmarks are usually identified manually from each of these images and these form the basis of subsequent...

Results on asymptotic and finite sample properties of an estimator of a nonlinear regression function when errors are spatially correlated, and when the spatial dependence structure is unknown are derived. The proposed method is based on a generalized nonlinear least squares approach, taking...

We consider Z1 and Z2 second-order stationary spatial processes. Our goal is to test whether the dependence structure is the same for both processes, that is, H0:f1=f2, where each fl denotes the spectral density of each observed process, for l=1,2. We study the asymptotic distribution for a...
