Abstract: Abstract This paper introduces a new extension of the Gompertz function for estimating the survival rates. The actual survival rates from USA life tables 2015 is considered for assessment process under the ordinary least squares method. A real data application is presented under the maximum likelihood method. The new Gompertz function is compared with many other competitive ones such as the Gompertz, the exponentiated Gompertz, the Rayleigh Gompertz, Weibull Gompertz, the Burr type X Gompertz and Rayleigh generalized Gompertz models.
