In the sortables section of Baseball Prospectus, there is a report called Batter Plate Discipline. If you’re trying to get a handle on how good hitters are at reacting to balls and strikes, this section contains measurements on such things as swing and contact rates. A natural way to divide such rates is based on the strike zone: A swing at a pitch inside the zone is a different event than at one outside the zone. A whiff on a pitch middle-middle is a disparate event from a whiff on a pitch way outside

FORECASTING - a method for translating past experience into estimates of the future. Forecasting is the process of making statements about events whose actual outcomes (typically) have not yet been observed. A commonplace example might be estimation of the expected value for some variable of interest at some specified future date. Prediction is a similar, but more general term. Both might refer to formal statistical methods employing time series, cross-sectional or longitudinal data, or alternatively

PROBLEMS 1. Calculate three forecasts using the following data. First, for periods 4 through 10, develop the exponentially smoothed forecasts using a forecast for period 3 (F3) of 45.0 and an alpha of 0.4. Second, calculate the three-period moving-average forecast for periods 4 through 10. Third, calculate the weighted moving average for periods 4 through 10, using weights of .70, .20, and .10, with 0.70 applied to the most recent data. Calculate the mean absolute deviation (MAD) and the cumulative

The writer cross tabulated attendance and price satisfaction and found 36% of attendees rated prices as fair, 45% as good and 12% as excellent. A regression analysis attendance (Y) and price (X) indicates that r2=.0465. The small r2 indicates a
