Applied Multivariate Statistical Analysis (2025) - Class #14, principal component analysis

This is a video from Applied Multivariate Statistical Analysis (STAT 494/873) at the University of Nebraska-Lincoln in fall 2025. See http://www.chrisbilder.com/multivariate (schedule and section materials web pages) for the course notes. The University of Nebraska-Lincoln (UNL) is recommending the elimination of my UNL Department of Statistics along with five other departments and other severe cuts. These recommendations include laying off 50+ tenured faculty--no other research university does this. There is a small chance that the Department of Statistics can be saved. Please let the university administrators know why statistics is essential to a research university, especially one that wants to get back into the Association of American Universities (AAU). Tell these administrators about your experiences with statistics. The administrators include: President Jeff Gold ([email protected]; leader of the University of Nebraska system) Chancellor Rodney Bennett ([email protected]; leader of UNL) Vice Chancellor Tiffany Heng-Moss ([email protected]; leader of the Institute of Agriculture and Natural Resources which includes the department) Academic Planning Committee, coordinator is Karen Griffin ([email protected]; the committee that recommended elimination of the Department of Statistics) You can also have your voice heard by submitting comments at https://apc.unl.edu/fall-2025-budget-reduction-feedback-form. If you choose to contact the administrators directly or to upload comments at the web page, please let me know. We have an October 10th meeting with the Academic Planning Committee to appeal their recommendation, so it will be helpful to know who is contacting them. UNL specific information about the proposed budget cuts is at https://budgetprocess.unl.edu/proposed-budget-reductions.
