Question:
In the squid data, all measurements are related to overall size of the beak. It may be useful to retain one measurement of size, say, W, and express the rest as ratios to W. The resulting ratios may then measure shape characteristics and exhibit less multicollinearity. Since the variables used in the regression are logarithms, the logarithms of the ratios are differences. For example, log(RL/W)=log(RL)−log(W).Using these redefinitions and keeping log(W) as is, we obtain the results shown in Table 8.14..
