Applied Multivariate Statistical Analysis (2023) - Class #3, matrix algebra

This is a video from Applied Multivariate Statistical Analysis (STAT 873) at the University of Nebraska-Lincoln in fall 2023. See http://www.chrisbilder.com/multivariate (schedule and section materials web pages) for the course notes. There is no "Class #2" video because it was an optional attendance class meant for those students without R experience.
