    The standard deviation is crazy huge on Montreal. Hard to believe that some of us have them as high as 1 and some as low as 12.

    We have an apple and orange problem--the previously posted table uses rankings from vividox and me based on our Elo and ELO+ ratings, respectively, which are intended mainly to reflect current team strength; but then it uses the HFA rankings from aperfectring that represent projections. It would be more consistent to use the latter's EAP rankings instead. I am not sure how the methodology of Jough matches up.

    Perhaps we also need another table combining the three sets of points projections:
    Code:

    The most notable thing here is how close our numbers are from top to bottom, despite three quite different approaches. Of course, most of the points have already been earned by this point of the season, so it makes sense for there to be convergence.

    While my model is projections, those projections come heavily from the current standings. At this point in the season, most teams have only ~1/7 of their schedule left. This means that my model becomes much less useful for projected point totals, since those will end up being basically just the standings table. The overall model is heavily based on goal ratio (goals scored / goals allowed), FYI. If the others also are, then they should behave relatively similarly, no matter the way that a game's probabilities are calculated.

    At this late point in the season, there is little freedom for the differences between the models to show up, at least if the models are doing a decent job of actually modelling the remainder of the season. I'm sure if we all went back to the midpoint of the season, we'd have much different results from each other.

    Here's my updated model results. Reminder HFA is a projection for the end of season based on the current standings and probabilistic results of the remaining games. EAP is a projection for the performance of a team over the course of a whole season against average opposition.

    Code:

    The east is still quite tight, and should be amazing to watch, especially for me since I have no real vested interest in it. The west in the current standings looks closer than it actually is. San Jose is only 1 point out, but they have played an extra game, so have less time to make up the gap. No one has locked up a playoff spot yet, and we are VERY late in the season for that to be the case now.

    San Jose faces Colorado and LA (and Dallas) to finish the season. So the Quakes do control their own destiny. I think. The permutations are always so complex.

    They are still counting on some of Colorado's and LA's results. If San Jose wins out, they have 53 points. If Colorado loses to San Jose and wins out otherwise, they have 54. Same with LA if they lose to San Jose and win out otherwise. This says to me that San Jose doesn't entirely hold their destiny in their own hands.

    I'm not pronouncing San Jose dead, far from it. However, they are still on the outside looking in, and hoping some results from games not their own go their way.

    Okay - thanks for that. I guess it wasn't really that complicated. Just checked both the schedules for the Rapids and Galaxy. The Rapids end the year with a home-away series with Vancouver (which is both odd and interesting). Seattle has Montreal (home) and Chivas, but end at Seattle.

    SCS gives SJE a 99.7% chance if they win out, so the Monte Carlo also found the combination that would keep the Quakes out. (Probably the same one(s) aperfectring found)

    Yeah, but the "winning out" is the real trouble there, especially with the road game to LA. My model came up with an ~4% chance of that happening. (42% win v Colorado, 19% @ LA, 49% v Dallas) It will get very interesting, though, especially if they win against Colorado.

    Seattle stays on top, LA is on the decline, and Columbus is +80 in the last month.

    In a special mid-weekend report! I am sitting around watching youtube videos when I see the results from today, and think, "wow, that just made it extraordinarily uncertain who would be the supporters shield winner".
    Here's the HFA update, which is much easier for me to put together. A full update will come early next week.

    Code:
    Tm  HFA
    SEA 56.5
    NYR 56.0
    SKC 55.6
    POR 55.2
    RSL 55.2
    COL 52.1
    LAG 52.0
    HOU 51.7
    MON 51.7
    SJE 48.0
    PHI 46.9
    CHI 46.7
    VAN 46.2
    NER 46.0
    FCD 45.5
    CLB 43.5
    TOR 29.4
    CHV 28.6
    DCU 18.2
    At this point in the season, I'd say that the expected deviation exceeds 1 pt, simply because there are so few games left that a single result could change it drastically. This means that there are realistically 5 (five) teams currently in the running for supporters shield. The only team among those which may significantly change is Portland, which plays at Vancouver tomorrow (Sunday).

    This season officially went from "that's a little unusual" to "what the fsck is happening here" status today. Usually at this point in the season, the supporters shield is either already won, or might as well be. But no, after this weekend, we will still have 4 teams, and possibly a 5th, which could all realistically win it. If Portland happens to win tomorrow (I hope they do), their projected point total should go up by nearly two points, but RSL and Portland have a game against each other meaning that RSL still would pretty much hold their destiny in their own hands, and should still be considered in the race.

    On the bright side, for sanity's sake, Columbus and Dallas pretty much ended their playoff hopes with their results today. While not mathematically eliminated yet, they are heavily relying on other teams' results to keep their chances alive.

    I'm going to go crawl back in my bottle of bourbon, because at least that acts somewhat sanely.

    Seattle getting destroyed by Colorado really knocked them silly (that one game set them back 28 points). They now share first with SKC. The top of the ratings is crowded with Seattle, KC, and LA within one point of each other and RSL, NY, and Colorado not far behind. At the bottom of the table, DC is threatening to dip down into the 1200s.

    Sounders are still projected as SS winners, but only by 1.19 points, and SKC is projected to finish over New York after they squandered points against New England at home this weekend. And on top of all of that, RSL and Portland are still projected to finish within 2.3 points of Seattle, meaning that right now, there are really five teams still in the SS race.

    Basically, my ratings are saying what the standing are already telling you: these next three weeks are going to be insane.

    This weekend almost completely destroyed any confidence in any team winning the Supporters Shield. I see 5 teams with a chance for it, 3 of those with a good chance. The playoffs are much closer to being set, but the East still has some murkiness. We are 3 weeks from the end of the season, and only 1 team has officially qualified for the playoffs. This season is bananas.

    The top of the ratings are so topsy turvy it's insane. SKC is only at +4 for the month, but is in first, LA is at -9 in the last month but at #2, Portland is climbing but not quite at the summit, Seattle is crashing harder than a Keanu Reeves movie, and Portland is currently predicted as the SS winner. Barely.

    Really though, I think with Seattle's loss tonight, the SS race is down to Portland, Salt Lake, New York, and Kansas City.

    The teams in the west just shuffled around their positions a bit, while those in the east were actually changed, with Chicago leapfrogging Philly. Nothing can really be said very strongly on this, though. Still no teams in the west have clinched, which means that with 2 games left for each team (LA can't clinch with their game in hand), we still have no teams which have actually made the playoffs there yet. Some good news there, though, is that one more team in the west was eliminated, so it is only 7 teams vying for the 5 playoff spots right now.

    In the supporters shield, New York holds their path in their own hands. Portland can tie them, but NY would win on the first tiebreaker. It is really looking like whoever between NYR, POR, RSL, and SKC can win their last two games will actually clinch it. POR and RSL face each other next week, and that is likely going to be one hell of a game, and will significantly impact the SS race, no matter which way it goes. So much on the line there, and all of the POR/RSL games have been ridiculous this year.

    Finally, this season is bananas.

    Lots of numbers flying around right now, so I'm going to update before today's games.

    Portland - RSL had huge repercussions on the Supporter Shield race. At this point, if New York wins out, it's theirs, and if they drop any points, SKC can claim it with a win in Philadelphia. If they both drop points, it's a bouquet toss and the maids' names are Portland, Salt Lake, and Los Angeles. My projected points total has SKC edging out NY by less than half a point.

    I now direct you to a number I didn't think I would ever see in my model. Seattle Sounders FC have moved -102 rating points in last month. Everyone knows Seattle has tanked in the last month, but to see it translated in numbers like that is, to me at least, incredible. If Montreal hadn't come from behind on Philadelphia yesterday, their movement in the last month would have looked similarly.

    2013.10.19.png

    Alright, so, we're all a fan of sportsclubstats.com, right? Me too. The one thing I'm not a fan of is all games are weighted the same way in the estimation. With the 50/50 method, both teams have a 1/3 chance to win, lose, or draw. With the weighted method, the model uses the average home win/lose/draw percentage over the last year. Well, that's really not practical. If, say, a very strong RSL side is hosting a very weak Chivas side in the last game of the season (wink wink), we would expect RSL to win that game. That is to say, using the average home performance over the last year doesn't really give you a good measure when a strong team hosts a weak team or a weak team hosts a strong team.

    Well, in my Elo rater, I come up with estimated win/lose/draw percentages for all the remaining games and add them up for the points predicted exhibit. So, if I run a Monte Carlo estimation using these game-to-game percentages rather than a flat average, I get a much more accurate picture of what my ratings are telling me the outcome will be.

    Now, there are a few limitations here. I'm not as good of a programmer as Ken from SCS is. His model, overall, is bigger and better, all the graphs that pop up when you highlight numbers is something I simply can't replicate. Also, he runs his model for 10B iterations, whereas mine bogs down at around 100,000 (he uses Python, I use VBA, there is a big difference in performance there). So I really just look at my numbers as supplementary to his - kind of an indicator of which way those probabilities skew given the remaining schedule.

    Here are my (rough) estimations using 10,000 trials:

    2013.10.19.MC.png
    Specifically looking at the SS numbers, I'm a few percent higher/lower than SCS on all of them due to strength of schedule. In particular, I have RSL at 10.9% (remember they host Chivas at home - a game they *should* win) whereas SCS has them at 8.3% using the weighted average method. That difference is solely due to using a expected outcome based off of rating and relative strength rather than a running average.

    Anyway, just one more way to look at possible outcomes that I thought I'd share.

    Something just feels wrong about Portland having a strength of schedule over 100 for their game against Chivas. I mean, I know why it is showing up as that, but still feels wrong.
