 In this section we test a model which does not use data for 0-2 year olds, and does not estimate these age groups. It is equivalent to the [[admb_real:admb_real#simple_model|simple model]], with the catch and survey data shifted. In this section we test a model which does not use data for 0-2 year olds, and does not estimate these age groups.
