Re: lecture 8: understanding bias
Well, when I wrote that one I was remembering the first time I tried using a polynomial fit program. (It was in Fortran 66, as a hint to how long ago that was.)
I fit an N degree polynomial to N points.
Even so, I believe if you fit a 99th degree polynomials to sets of 100 points you will have a large variance, as did the 1st degree to two points. It won't be easy at all to visualize, though.
