Site accuracy, updated models, admissions game

Friday, November 9th, 2007

Today I updated the prediction models for the first time in a few months, so you might see a shuffle in your predictions as the model updates. We’re still working with a relatively small sample size in the low thousands. As the site grows, the predictions will become less labile.

As things currently stand, the site is, on the whole 90% accurate (see the bottom piece of data on that page).

Also, the Admission Game has been updated to properly take into account the predictions made by each school’s model.

Probability and accuracy

Wednesday, November 7th, 2007

Welcome, CCers. After getting some feedback requesting more information, I’ve made a couple changes. First, you will now see the predicted probability of admission in your profile, instead of just a “yes” or “no”. Second, the accuracy of the model that is giving you the prediction will be shown just below, so that you can get a better sense of how much you want to trust the prediction.

Cheers,

James
