That was the "mid-to-high teens" one that got me to make the post on how badly tracking underestimated Passion of the Christ (according to that Marich book). Sometimes these "tracking" announcements are atrocious, but can have a significant effect when posted around here, even if they aren't tagged.

So maybe you should have a Bonehead Prediction of the Week award, Variety winning for SOGOD this week. Make sure to use the prediction as the base, instead of the Sunday estimate that makes it sound better.

Smile

You could also have a Best Prediction award, though again the timing of predictions may be a factor. BOM looks best on SOGOD, but when was that one made for example?

Difference between regression model and weekend estimates were, NONST: 19.67%, SOGOD: 15.36% elchan2012 Mar 02, 08:25

Do you think there's enough variation in the data points. Most the the predictors are engaging in group think or looking at the same trackin {nm} Moviesnob Mar 02, 09:01

Yes, there is sufficient variance. The mean standard deviation between the forecasters over 4 years is 2.84. (zero being no variance) {nm} elchan2012 Mar 02, 09:18

The regression model will account for the boneheadedness. If they consistently low ball, or high ball, they are weighted lower. {nm} elchan2012 Mar 02, 10:06

What the regression will do is find the relationship between the forecasters predictions and the weekend estimated BO. elchan2012 Mar 02, 10:19

The Bonehead winner each week could be fun though. :-) Also, calling it a regression model doesn't make it much more than what it mainly... KalElFan Mar 02, 10:41

Of the we reporting consistently for 4 years, here are the average error rates. (Box Office has been the most accurate) elchan2012 Mar 02, 11:28

The concept of a regression analysis is that there is an independent variable and a dependent variables. The OW is not dependent on the GMov Mar 02, 10:12

What about this KurtPilo Mar 02, 11:58

I thought it was using HSX stock price as the dependent variable. otherwise, you're right and a weighted average is more appropriate. {nm} Moviesnob Mar 02, 12:21
