Closing thoughts

As I said at the beginning of the year, my sole aim this season was to build a predictive model worth a damn, just to see if it could be done. In the end, the model was 93% accurate in calling people safe (including winner Candice Glover tonight) and picked the person eliminated 78% of the time (89% of those eliminated were ranked either first or second most likely to go, FWIW). That’s pretty decent.

The site found an audience, as well, which I suppose I’m happy about. The site was the top Google search for “Idol predictions” as of yesterday, and about 6000 unique visitors showed up to see the (thankfully correct) call of Candice as winner. About 3000 people found their way to the site weekly, on average, during the finals.

Prediction coming soon, but Candice is already way ahead

The official model call will be posted as soon as WNTS ratings are posted, but those don’t matter all that much at this stage. Candice is handily beating Kree on both Dialidol and Votefair, and that by itself is enough to put her at a 75% chance to win, versus only 25% for Kree. If WNTS ratings come in like I think they will, it will be a clean sweep. Check back for the official numbers after Dialidol equilibrates a little, but I have Candice at about 1:3 odds at present.

Season 12 model accuracy assessment roundup

As we head into the finale, it’s time to look at how predictable the season has been, particularly with regard to the three prediction models on this site. The first is the semi-finals model, predicting who would be in the finals. The second is the finals model, a week-to-week guess as to who would be in the bottom group, safe, and/or eliminated. Finally, the Top 3 Tracker, which tried to guess who the Top 3 would be.
