Bayesian Framework for Simultaneous Registration and Estimation of Noisy, Sparse and Fragmented Functional Data
James Matuk, Karthik Bharath, Oksana Chkrebtii +1
In many applications, smooth processes generate data that is recorded under a variety of observation regimes, such as dense, sparse or fragmented observations that are often contam…
Automatic Detection and Uncertainty Quantification of Landmarks on Elastic Curves
Justin Strait, Oksana Chkrebtii, Sebastian Kurtek
A population quantity of interest in statistical shape analysis is the location of landmarks, which are points that aid in reconstructing and representing shapes of objects. We pro…
Radiologic Image-based Statistical Shape Analysis of Brain Tumors
Karthik Bharath, Sebastian Kurtek, Arvind Rao +1
We propose a curve-based Riemannian-geometric approach for general shape-based statistical analyses of tumors obtained from radiologic images. A key component of the framework is a…
A Geometric Approach to Visualization of Variability in Functional Data
Weiyi Xie, Sebastian Kurtek, Karthik Bharath +1
We propose a new method for the construction and visualization of boxplot-type displays for functional data. We use a recent functional data analysis framework, based on a represen…
