Topic

This workshop is part of a collaboration between the anthropology, statistics, and stochastics departments in Freiburg and Penn State on statistics for geometric data and applications to anthropology. With the proliferation of affordable biomedical imaging technologies, the statistical analysis of 3D shapes has become an important task in biological sciences. Ignoring their inherent structures and complexities can bias scientific conclusions, especially when there is large shape variability. This workshop addresses a blend of fundamental theoretical questions and applied problems with the goal of expanding the fields of functional data and shape analysis, focussing on anthropological applications.

This is a follow-up to the previous workshop at Penn State University in June 2018.
