| ### Model description The catch-age model from Schnute and Richards (1995) has been used compare the computational speed of AD Model Builder with other statistical software packages (see her). It is conceptually appealing to assume that the annual recruitements are random effects, i.e. they are drawn from a common normal distribution. The random effects module then lets you estimate the mean and the variance of the normal distribution. The model is memory consuming and requires the following command line options in order to run smoothly: caest -est -l1 30000000 -l2 100000000 -l3 100000000 -nl1 10000000 -nl2 10000000 -nl3 10000000 The computational time is 31s on a 2006-pc running linux.
