The won‐loss percentage for all games played in a season by NBA teams is modeled as a function of team performance statistics. Four variables field goals, free throws, rebounds, and turnovers are found to be statistically significant and account for more than 90% of the variation in the data. The regression coefficients also appear to be stable from year to year. Predictions for four years obtained from the estimates of one season show good agreement with the observed data. Forecasts for the 1993 season are also given based on mid‐season statistics. Predictions for play‐off winners are also briefly discussed. The analysis is carried out in the spirit of exploratory data analysis using graphical methods.
