I have successfully defended my Ph.D. dissertation: “Parsimonious B-Spline Regression Models via Control Polygon and Control Net Reduction for Identifying Factors Explaining Variation in Daily Hormone Profiles During The Menopausal Transition.”
Only minor edits to make to the dissertation itself. Several publications are forthcoming. You can get more info on the control polygon and control net reduction methods from the R package cpr available on CRAN , github.
update: 2024-10-01 A website for the cpr package can be found here.
