Trends in Northern Hemispheric Snow Presence
Yisu Jia, Robert Lund, Jiajie Kong +3
This paper develops a mathematical model and statistical methods to quantify trends in presence/absence observations of snow cover (not depths) and applies these in an analysis of…
Scaled torus principal component analysis
Pavlos Zoubouloglou, Eduardo García-Portugués, J. S. Marron
A particularly challenging context for dimensionality reduction is multivariate circular data, i.e., data supported on a torus. Such kind of data appears, e.g., in the analysis of…
Non-Euclidean Analysis of Joint Variations in Multi-Object Shapes
Zhiyuan Liu, Jörn Schulz, Mohsen Taheri +4
This paper considers joint analysis of multiple functionally related structures in classification tasks. In particular, our method developed is driven by how functionally correlate…
New Perspectives on Centering
Jack B. Prothero, Jan Hannig, J. S. Marron
Data matrix centering is an ever-present yet under-examined aspect of data analysis. Functional data analysis (FDA) often operates with a default of centering such that the vectors…
Persistent topology of protein space
W. Hamilton, J. E. Borgert, T. Hamelryck +1
Protein fold classification is a classic problem in structural biology and bioinformatics. We approach this problem using persistent homology. In particular, we use alpha shape fil…
diproperm: An R Package for the DiProPerm Test
Andrew G. Allmon, J. S. Marron, Michael G. Hudgens
High-dimensional low sample size (HDLSS) data sets emerge frequently in many biomedical applications. A common task for analyzing HDLSS data is to assign data to the correct class…
