Changed high school age calculation to overage when entering eighth grade so the model can be used throughout the year.
New 8GM specification with three changes -- using overage in 8th grade, removed Classical, and rescaled attendance to be easier interpretted.
Commented out ctree -- I don't think it will add much to the district understanding.
Updated prose to reflect models.
Commented out model comparison because it's no longer relevant and adjusted subsequent charts.
Reflects overage change.
Clearer labeling
Fixed a duplicate student record issue with deeper filtering.
Updated original model and quarter 1 model with the new data sets. Fails dropped out again.
TODO note about updating values in prose.
