What the article doesn't mention - and this is a more practical consideration - is the accuracy of the modeling data that pi might be applied to. Most measurements in practice are probably not good to more than four or five significant figures, if that, at least in the social sciences. I used to give students as an exercise to add a random digit at the accuracy limit and see how it affected their model estimates. Throw in a little multicollinearity and there you are. See the famous Morgenstern book A Perspective on the Accuracy of Economic Observations on JSTOR and some updates (behind a paywall, unfortunately) On Mon, Mar 15, 2021 at 9:38 AM Andy W <[hidden email]> wrote: Well Bruce, at least your solution is good enough for government work, |

Since we're on (Covid) memory lane: "I'm playing . . all the right notes, but not necessarily in the right order!" as Eric Morecambe famously declared to André Prévin in the brilliant 1971 sketch Grieg's Piano Concerto (8'04''). https://www.youtube.com/watch?v=r7yb-JncKow (For some reason Youtube thinks my computer is still in France: if you can't get round the BBC copyright block, it's available on https://www.dailymotion.com/video/xds7am ) . -----Original Message----- From my undergrad days as a philosophy major.
