For white men in the United States, Table 14.14 presents the number of deaths per thousand individuals of a fixed age within a period of a year.

(a) Plot x = age against y = death rate and against log y.
What do these plots suggest about a good model for the relationship?

(b) Find the correlation between (i) x and y, (ii) x and log(y). What do these suggest about an appropriate model?

(c) Using generalized linear models, find the prediction equation for the model log[E(y)] = α + βx.

(d) Find the prediction equation for ˆy. Interpret the parameter estimates.
