Also note that case 182 is a particularly lean llc accu measure body fat tester individual whose predicted percentage of body fat is negative according to Siri's and Brozek's equation and has been truncated to zero in the dataset. 9 (b) Choose one of the two percentage of body fat estimates, either Brozek's method or Siri's method. Fit this percentage of body fat in terms of some subset of the remaining llc accu measure body fat tester variables excluding density, which is not easily measured. The researchers who collected these data, Penrose, Nelson, and Fisher (1985), built a regression model for fat free weight = (1 - fraction of body fat) * weight that used the variables weight, age, age^2, height, and (abdomen - wrist). Do you find any of these variables useful in fitting percentage of body fat?
