I’ve thought highly of the Ranker’s NCAA Basketball picks against the spread, and I’ve been itching to compare they’re accuracy against the predictions from other computer models.
I’m not the quickest draw when it comes to scraping the web for data, but I’ve begun comparing the Ranker’s predictions with those from ESPN’s BPI predictions.
I can only compare the picks for games that the Ranker made picks for. I’m comparing all of the Ranker’s picks, as well as the subset of her picks that she was most confident about.
So far…good job, Ranker!
