It was originally devised by Bill James as a way to predict the outcome of a game based on two teams' respective win-loss percentages. This is ideal in our case since our focus is the prediction of a win or loss, not a numerical value. Lyle compared these techniques against existing baseball prediction systems such as the Player Empirical Comparison and Optimization Test Algorithm (PECOTA) (Silver . We use previous score and pitcher data to best attempt to estimate the results of each game. He is also the creator of the baseballr package for the R programming language. For each team, x will be the difference between their runs scored and runs allowed (x = RS RA), y will be their actual observed winning percent (W%) and y is the teams expected winning percentage EXP(W%) based on (RS RA). Some will cost you a pretty penny. One advantage of the Linear Formula over the Pythagorean Formula is it is easier for a general manager to understand and use. Appligent AppendPDF Pro 6.3 Read more about our business model here. On average, some players will do better and some players will do worse. You want to score runs, and you want to be consistent.". Equation 5, An Application Of The Linear Formula For Baseball. The extra team was caused by a tie between Tampa Bay and Texas. The actual derivations will be provided in a section near the end of this paper. Because of the strong positive correlation between x = (PS PA)W% and y = (PS PA)2 in Equation 3 for both the NFL and NBA (see Figures 3 and 4), we can use 650.36(PS PA)W% 39,803 (from Equation 3) to replace (PS PA)2 in Equation 2 for the NFL and 2850.8(PS PA)W% 673,540 to replace (PS PA)2 in Equation 2 for the NBA yielding a new Equation 4 for the NFL and a new Equation 4 for the NBA. Using the difference between the runs scored and runs allowed in the previous year as a starting point, a GM can plan to increase that difference to benefit his team. Equation 1. Now you have a clear understanding about what data can do in order to help you with baseball predictions. 34 0 obj His formula for estimating the probability that team X beats team Y, which James referred to as the log5 method, is given by the following equation: relevant to predicting an outcome of a baseball game than others. The current projection system for Major League Baseball games is at Level 3, our highest level of analysis. endobj endobj 555 N. Central Ave. #416 (Pitchers who havent started before are assigned a below-average rGS, but that score is more influenced by each successive start than the score of an established pitcher.) To train the algorithm, it is important to find an appropriate dataset. (2) y = W% = (1/T)*W = (1/T)*(n/2)T = n/2, (4) b = [(n/2)(PS PA)2 0] / [n(PS PA)2 0] (The average is about 1500.) We rate the accuracy of baseball projections by comparing each source's player predictions to the actual statistical outcomes. Bill James introduced a formula for estimating a teams expected winning percentage in the major leagues based on the number of runs they scored and allowed. However, the exact methodology followed to determine the winner can vary from one algorithm to another. <>/Metadata 2 0 R/Outlines 5 0 R/Pages 3 0 R/StructTreeRoot 6 0 R/Type/Catalog/ViewerPreferences<>>> You may also be interested in our Winning Percentage Calculator, A collection of really good online calculators.

The above derivation is based on the assumption that each team played their scheduled T = 162 games. Because of the strong positive correlation between x = (RS RA)W% and y = (RS RA)2 in Equation 3, we can replace (RS RA)2 in Equation 2 with 1464.4(RS RA)W% + 32,710 (from Equation 3) giving us Equation 4 below for the expected winning percentage for a team. For the NFL, EXP (W%) = [(PS PA)W% / 650.36(PS PA)W%]*(PS PA) + 0.50 Learning how to do this (and its fairly simple these days with the great range of intuitive software available) will save you hours if not days or weeks in data collection. And we can tell you, while no sports betting model you build will be light work, the first model for sports betting that you build is always the hardest. Heres how each of those interactives work.
