If a sports time series, such as attendance, is nonstationary, then the use of level data (e.g., demand estimation using panel data) leads to biased estimates, and the direction of the bias is unknown. In past works, authors have failed to reject nonstationary data, taken first differences, and...

From historical odds Cain and Haddock assign the probability of a tie at 25% and offer functional forms for the standard deviation of a league with equal chances of a win for each team under different point assignment schemes. They then track the ratio of actual to these idealized standard...

League-winning percentage Gini coefficients have seen recent use as measurements of within-season competitive balance in Major League Baseball. The authors demonstrate that the zero-sum nature of league play renders past estimates inappropriate. Adjusted for league play, Gini coefficients reveal...
