Abstrakt:	There are many models for mortality rates. A well-known problem that complicates modeling of human mortality rates is the "accident hump" occurring in early adulthood. Here, two models of mortality rate based on power-exponential functions are presented and compared to a few other models. The models will be fitted to known data of measured death rates from several different countries using numerical techniques for curve-fitting with the nonlinear least-squares method. The properties of the model with respect to forecasting with the Lee–Carter method will be discussed. [ABSTRACT FROM AUTHOR]
