Daniela Witten on the Singular Value Decomposition

A new Twitter account came to my attention a few days ago: @WomenInStat (Women In Statistics and Data Science).  Every week a new moderator is chosen to field questions.  When I discovered the group the moderator was Daniela Witten (@daniela_witten).  Dr. Witten is a Stanford alumnus.  Here’s her official title.  Her publications bring statistical methods and data analysis to biostatistics, a field sorely in need of her help. Her Twitter thread is a discussion of the singular value decomposition (SVD).

Her thread discussing the SVD is below.  I’m posting it here because I’ve been getting too many views on my other articles.  Be warned, this is hard-core statistics.  Read at your own risk.
