Webparameter and 1= the scale parameter.) There is no explicit formula for the hazard either, but this may be com-puted easily as the ratio of the density to the survivor function, (t) = f(t)=S(t). The gamma hazard increases monotonically if k>1, from a value of 0 at the origin to a maximum of , is constant if k= 1 Webuses a second derivative assessment of the variance of the joint density with respect to the ETAs. The Laplace method is used when nonnormal densities are used to model some of the observed data or the prediction model imparts a high degree of nonlinearity to the joint density of the individual parameters.
