Video – Introduction to Statistics part 1

So I’m set up for recording video again. I’ve got a new prep this semester: Business Statistics. The videos should combine with the ones I’ve already posted to create a full 2-course sequence in statistics for business applications. My goal is to post one every Tuesday and Thursday. I hope you enjoy! As always, feedback, positive and negative, is welcome.

Economics is a science. An awesome science. Newton, Feynman, Maxwell, Hooke, et al. would agree.

I wrote this in reply to a list-serv conversation with some criticisms of economics as a  science, and since I still work for my supper, I figured in addition to making lemonade, I would clone that lemonade with the handy-dandy Replicator function on my futuristic writing contraption.

In the intervening years, a number of economists sacrificed completeness and consistency for external validity, and that blinded us (well, them; I’m not a macroeconomist) to the causes and cures of the recent financial crisis. He pitches it as a saltwater v. freshwater battle, which maybe it is.

Then again, maybe it’s a matter of getting high off your own supply. Read the rest of this entry »
