Perhaps more than in any recent season, there's still of lot of "conditionality" in the final home-and-away season ladder, by which I mean that knowing where Team A finishes tells us a lot about the likely finishes of other teams.

A loss by GWS and a lacklustre performance by Geelong saw both teams' chances of the Minor Premiership decline significantly this weekend, in GWS' case into near non-existence.

MoSSBODS right now is very much a Crows fan - some might say too much of a fan - and that enthusiasm reveals itself quite clearly in the results of the latest simulations.

I'm fairly sure it'll not be entirely surprising to you when I say that this week's results put a significant dent in the Top 4 aspirations of Adelaide and the Western Bulldogs, bolstered the Finals hope of the Roos at the Saints' expense, and made the Dons more likely Wooden Spooners and the Lions less likely to collect that item of cutlery.

The Roos did just about enough this weekend to secure the final spot in the 8, though an upset victory over the Dogs and Port Adelaide's loss to the Giants, left a very small door open for the Saints. They're now 14% chances of taking that last place while the Kangaroos are 84% chances.

From a "who plays the Finals" point of view, last week's results were most encouraging for Port Adelaide (+14%) and St Kilda (+6%), and least encouraging for the Kangaroos (-21%).

Geelong's loss to Sydney this week put a considerable dent in their Minor Premiership prospects, at least according to the latest MoSSBODS-based simulations (see last week's post for details of how these simulations are performed)

This week, I've used the same methodology as I did last week, but expanded the number of simulations to 100,000, which means I've doubled the precision relative to last week's estimates (since four times the number of simulations provides twice the precision). It took about 7 hours to run the simulations, but that's a small price to pay for added precision (he offers, self-affirmingly ...)

This year I'm starting simulations for the Finalists a bit earlier than usual, partly as a result of a request from Twitter follower @SgtButane, who's another of the burgeoning group of AFL fans using statistical modelling techniques to forecast game outcomes. If you've an interest in this sort of modelling and you're not yet on Twitter, I'd strongly encourage you to sign up and start following like-minded people (I'm @MatterOfStats by the way). There's a tremendous amount of informed commentary and quality analysis being shared by some very talented people in this space.

After Week 1 of the Finals, six teams are still capable of winning the Flag and nine Grand Final pairings are still possible.

This year, I think the trickiest part about forecasting the Finals series is deciding how relevant recent Finals history will be in the current season.

The Eagles' victory over the Dockers considerably enhanced their chances of taking out the Minor Premiership, though the Eagles' gain came at the expense not of their immediate opponents but instead of Hawthorn, whose loss to Port Adelaide all but ended their hopes of this minor honour.

The previous post here on the Simulations blog triggered an interesting exchange of comments with Rob that forced me to think a little harder about the appropriate interpretation of the results presented in that original blog post.

Imagine that the TAB Bookmaker was exceptionally good at his job and that his assessments of every game this season were what a statistician would label an "unbiased estimator" of the final result.

The ChiPS System, on whose opinions I've been basing this year's Finalist simulations, thought Fremantle would go down to the Eagles last weekend, and also that Hawthorn would win.

Fremantle clearly increased its chances of taking out the Minor Premiership this last weekend in defeating the Saints while the Eagles went down to the Hawks. That said, the Dockers still face the Eagles as the home team at Subiaco, as well as the Roos and the Power as the away team, so they're not yet certainties, some in the popular press' views notwithstanding.

Well that last weekend certainly changed things a bit

The latest round of simulations has one of Hawthorn, West Coast or Fremantle taking out the Minor Premiership in all but a handful of replicates, and Hawthorn collecting that prize about half of the time. I find it hard to imagine a time in recent history where a team 3rd on the ladder so late in a season is such an overwhelming favourite for this honour.

Last weekend's results made the Hawks almost even-money prospects for the Minor Premiership and all but extinguished the Swans' already-slender hopes for that same title.

I've been part of some interesting conversations this week on Twitter about definitions of "close" and "blowout" games of Australian Rules.
