  1. Linear Regression The Science of Predicting Outcome

  2. Is the fraction of the variation in the values of y that is explained by the least-squares regression of y on x 40% of the variation in y is explained by the least-square regression of y on x r2 :coefficient of determination a=.0987 b=2.3234 r2=.40997 r=.6502

  3. 80% of the variation in the predicted BAC is explained by the least-square regression of BAC on number of beers consumed. Your Turn Interpret the coefficient of determination generated by this computer output.
