Driving to FL... ...working on the DrJoeIndex...

Well...

I am off to FL by way of a stop at the In-Laws in GA.

I am going to keep busy during the drive (when my wife
is driving and the kids are not screaming ;-) by trying
to formulate a DrJoeIndex for each team at the Nationals.

The DrJoeIndex would go something like this:

Calculate every team's average score at a regional
(already done).

Calculate every team's standard deviation for their
scores at each regional (easily done).

The DrJoeIndex is then calculated as follows:

The sum over all Matches of

The sum over all partners of

(the score for that match - the partner's average
score) / the partner's standard deviation

Once I have each team's DrJoeIndex, I will rank
calculate DrJoesRank based on the index.

The idea behind the DrJoeIndex is to calculate the aid
(or anti-aid) a team gave to the alliance by giving a
team more points for helping alliance partners beat
their average while taking points away for holding
alliance partners below their average.

I am not seriously considering this a real method of
calculating a team's rank at a competition, but I am
curious about how to calculate a team's "true"
contribution to the alliance.

I am sure that everyone can think of examples where teams
that seem good are ranked low as well as examples teams
that seem so-so were ranked near the top.

I am interested to see if
there is some method of teasing out this kind of thing
from the data.

It will be a fun way to pass the time in any case.

Stop by the pits in FL to see if I have found any
diamonds in the rough (if they and you are not in Curie
Div. I may even name names! ;-)

See you in FL.

That sounds so much like what a friend and I picked to do for our statistics project it's scary! It'll be interesting to see what the 2 sets of conclusions look like!

Sounds like a really fun drive down to Florida...

I wish I could drive to Florida myself, but few reasons forbid me to do such thing:

First I don't have a driver's license because I never really like cars.

Second the drive will be too long for me to get back for my two midterms the Tuesday right after Nationals.

Third I have to study Multivariable Calculus on the way to Florida...

Hope you have fun working with the index, and with kids on your side.

See you in Florida.

oooh......

I wanna see it!

I swear, if there is one thing really good about this competition, it's the amount of data we have to work with. ;) My stats teacher loves it....

If I had the time, I'd do that, but I'll try to come up with something else to compliment it.

Love the idea! It sort of reminds me of total average in baseball (although the computation sounds more like the QB index in football). One suggestion, though: wouldn't it make more sense to average a team's ranking over the number of matches? That would give a number that can more easily be compared between teams that have played different numbers of matches.
