Recently I'd been noticing some traffic to the site from the Big Footy website where the Forum members had been discussing the relative strengths of Bulldogs teams across VFL/AFL history. That, coupled with my continuing desire to become more proficient in the ggplot2 R package of Hadley Wickham, dragged me out of my off-season blog malaise to perform the analyses underpinning this current posting.
In the previous blog we looked at the average level of surprisals generated by teams and by team pairings across all of VFL/AFL history and during the most-recent seasons. Today, as promised in that blog, I'm going to analyse surprisals using the same general methodology, but by season.
The original motivation for this blog was to provide additional context for the previous blog on victory probabilities for portions of games. That blog looked at the relationship between the TAB Bookmaker's pre-game assessment of the Home team's chances and the subsequent success or otherwise of the Home team in portions - Quarters, Halfs and so on - of the game under review.
