I’m deeply greatful to Hui Lin and the inimitable Yihui Xie for arranging for me to give a “virtual seminar talk” to the Central Iowa R Users Group. You can view my talk, including an interesting Q&A session, online. (The actual start is at 0:34.) There are two separate topics, my regtools package (related to my forthcoming book, From Linear Algebra to Machine Learning: Regression and Classification, with Examples in R), and the recent ASA report on p-values.
