In this week’s episode Greg and Patrick invoke the very personal interpretation of modern art as a framework for thinking about the exceedingly cool topic of rotation in exploratory factor analysis. Along the way they also discuss Venice Beach, haystacks, drug fronts, being insufferable, ignoramuses, .22’s and stop signs, weak pivots, honking factors, pooping out matrices, the Gulf of America, twitchy eyeballs, big fat zeros, obliquity, and Extortomax.
