If you're not as programmatically inclined, you can use a GUI with JavaScript

I've tried to be consistent on how to handle renaming and merging, but may not have entirely succeeded. It's also possible that a .txt file was downloaded under slightly different conditions in tourneys.json.

From start to finish, python analyze.py takes about 30 (wild guess) minutes. But it saves its results along the way, so if you get bored you can interrupt and restart the process. You can also do this if Pywikibot's throttling starts to become too onerous.

The documentation of the Python and Javascript files can be generated by pdoc -o docs *.py and jsdoc -c jsdoc.conf.json, respectively.

There are a large number of files created along the way that are .gitignored: * {group}/{tournament}/{year}.txt: the content of that year's entry in Wikipedia * {group}/{tournament}/None.txt: same as above, but all the tournaments are on one page * [group/[tournament/]]state.csv Each (normalized) university and its state * [group/[tournament/]]winloss.csv The matrix of counts of seed defeating seed * {group}/{tournament}/winlossplot.tex * {group}/{tournament}/winlossprobs.tex

Reseeding files: * [group/[tournament/]]reseed.csv How much each university should be reseeded * [group/]reseedfiltered.csv Same as reseed, but trimmed down so that points not plotted by TeX don't appear (it had trouble with the file size) * [group/]reseedapprox.csv Same as reseed, but a linear approximation of its components * [group/[tournament/]]statereseed.csv Same as reseed, but grouped by state * [group/[tournament/]]tzreseed.csv Same as reseed, but grouped by timezone

We are able to apply this code to fifty-eight thousand games to estimate the probability of an upset solely as a logistic function of the difference in seeding. We are also able to examine how well or poorly a team performs compared to its seeding. We conclude that the only team that is consistently underrated is \textbackslash your\_favorite\_team, while the only team that is consistently overrated is \textbackslash your\_hated\_rival.} } Non BibTeX citation styles are also available at the Scatterplot website.
