  1. Very cool. So does the @Risk package effectively save you from having to create data tables for every match and then totaling everything up at the end (as I reworked the sheet from the book to have data tables for the winner of each region plus the outright winner - but to do data tables for every match in one sheet would probably stretch my laptop).

  2. Wayne,

    As a Hoosier, I can’t be disappointed with the great season. Do you have a suggested point adjustment for the loss of Verdell Jones?

  6. My one regret from being at IU and in Kelley was not taking a class one of your classes.

  7. Hi Wayne,
    Sagarin ratings give you a number of points for each team. What stochastic component do you add to do the simulations?
    Thnak you!

    Comment by Michael — March 13, 2012 @ 10:59 am

  8. I think he costs us a point or 2 becuase Abell needs to play more

  9. 10 point std dev about prediction

    Comment by wwinston — March 13, 2012 @ 11:46 am

  10. Thanks. Best of luck in future

    Comment by wwinston — March 13, 2012 @ 11:46 am

  11. Hey Wayne, I have an interesting question… You say there were 5,000 simulations done. Of the 5,000 simulations taking 2011 as the example (last year), were any of the simulations 100% correct or predicted the final four? If so, how many were correct and if not, what was the closest simulation percentage wise? I’d be curious to know the same thing when this years tourney is all said and done.
