SEBA Projections

SEBA Projections through July 24

Welcome to the Statistical Extrapolation Bayesian Analyzer Projection System, which is, of course, a tortured gathering of words used to form the SEBA Projection System.

The system consists of a model projecting the probabilities of game results and then a barrage of simulations which account for the remaining luck. So the probabilities you see below show, essentially, what the odds are of an outcome if the team continues to play like it has been.

Below are the current season forecasts using data from MLS games through July 24, 2016.

Power Rankings

The “Power Rankings” we concoct are the actual “strength” of the team according to competitive expectations. They are computed showing average expected points result if every team in MLS played every team both home and away.

SEBA has the Union remaining at No. 4. I would have expected a drop, but SEBA treats recent matches as the same weight as early-season matches. ESPN has the Union down 5 at No. 12. SI also has them drop 1 to No. 8.

Playoffs probability and more

The following charts show the probabilities for making the playoffs, winning the Supporters’ Shield, winning the MLS Cup, winning the USOC Cup, and qualification for CONCACAF Champions League.

The Union went down to 89.3% from 93.4% last week in their probability of making the playoffs.

Philadelphia fell further to 0.8% from 1.7% in their odds of claiming the Shield.

mlsGraphs2016-07-25-page-007

The Union dropped significantly from 9.1% last week to 6.5% in their odds of capturing the MLS Cup.  Philadelphia’s competition for a first round bye got very steep which causes a significant penalty.

Philadelphia was eliminated from the US Open Cup.

mlsGraphs2016-07-25-page-009

The above shows how the model rates each U.S. league & conference compared to one another. This is based on an all vs. all assessment rather than a top vs. top assessment. MLS is clearly rated as superior to either NASL or USL. USL has a slight edge over NASL. This also shows the MLS-West outperforming MLS-East and USL-East slightly outperforming USL-West.

mlsGraphs2016-07-18-page-010

Philadelphia’s probability of qualifying for the CCL plummeted from 46.1% to 29.4%. The USOC loss caused a lot of the drop as well as the increasing competition for the Eastern Conference regular season champion.

Philadelphia finishing

The following shows the probability of various playoff categories and Philadelphia’s probability of each of them.

The following is a “density” chart showing the relative probability of Philadelphia finishing at the different after-playoffs rankings from 1 to 20.

mlsGraphs2016-07-25-page-015

The following is the list of Philadelphia’s remaining scheduled matches accompanied by result probabilities as predicted by SEBA.

mlsGraphs2016-07-25-page-016

The charts below shows the average results of all the simulations and the probabilities associated with all of the above. The chart is broken up into two parts in order to better fit on your screen.

(Note: CCLAlternate refers to qualifying for CONCACAF Champions League non-traditionally. U.S. teams qualify by winning the MLS Cup, winning the Supporters’ Shield, winning the Conference in the regular season, and by winning the U.S. Open Cup. If a Canadian team wins any of these or a U.S. team wins more than one, the extra slots are filled by top regular season performers.) (Also, “regSeasFinish” refers to finishing the conference in first place AND not winning other CCL slots like MLSCup, Supporters’ Shield, and USOC)

Changes Over Time

This chart shows how Philadelphia’s chances at each of the outcomes has evolved over the course of the season.

Records

It should be noted that, with both of these tables, it shows the odds of breaking MLS single-season records, not of holding them. If more than one team would break the same record this season, they would both be represented below.

The following table shows Philadelphia’s odds at breaking various MLS single-season records

The following table shows all single-season records that had at least one simulation break the record. However, it limits the records to show only the most probable team for breaking each record.

USL Projections

Bethlehem decreased to 19th from 18th and Harrisburg City Islanders increased from 25th to 24th. USLSoccer.com‘s top 10 rankings do not include either team.

uslGraphs2016-07-25-page-005

Bethlehem’s probability of making the playoffs rocketed back down from 59.9% to 39.9%. Harrisburg City’s increased to 4.2% from 1.6%.

uslGraphs2016-07-25-page-006

Both Bethlehem and Harrisburg City have no chance of winning the USL regular season title.

uslGraphs2016-07-25-page-007

Bethlehem’s probability of winning the USL Championship decreased from 2.5% to 1.2%. Harrisburg City’s chances increased from negligible to 0.1%.
