The Astros have a 53% chance of winning 83 games in 2009

I was inspired to get fancy by BtB and plugged the Astros WAR Projection Project into a binomial distribution function to determine what the probability was that the Astros actually hit the mark our input projected.  The actual probability was .531, so I understated the probability, slightly, in the title.

I know this isn't entirely accurate, but I thought it would be fun none the less.

When statistical analysis goes too far….

Ceci n'est pas une signature.

YOU DON’T PLAY BASEBALL WITH CALCULATORS, DAMMIT!

Seriously though, good job. Can you figure out what the probability is for 90 wins?

A good friend of mine used to say, "This is a very simple game. You throw the ball, you catch the ball, you hit the ball. Sometimes you win, sometimes you lose, sometimes it rains." Think about that for a while.

Nevermind

Like a jackass I put in the cumulative probability. I got 6.26% (I still can’t figure out where the disconnect is, I used 83, 162, .512345679, and 1).

I should really not be blogging at 5:00 AM at the peak of insomnia.

My formula is:

=100-(100*BINOMDIST(O23/2,81,0.51234568,1))

With O23 set to 83, or whatever wins total you want.
