| Zusammenfassung | This technical report presents a description of two SAS programs (MAKED.SAS and SEAL.SAS) that fit a population dynamics model to seal (Phocidae) data. The programs have been constructed in such a manner that special knowledge of SAS is not required to run them. The population dynamics model is transformed to a standard nonlinear regression model and parameters are estimated using SAS's PROC NLIN. Output from the programs includes estimates of intrinsic mortality, pup numbers over time and total population numbers over time. The code for the programs is presented along with two examples. | ||||
