A NOTE ON THE EXTENDED GOMPERTZ GROWTH MODELS

Nikolay Pavlov, Vesselin Kyurkchiev, Anton Iliev, Asen Rahnev, Nikolay Kyurkchiev

Abstract


Following the ideas given in [18], in this article we study a hypotheticalpiecewise smooth extended Gompertz growth function B(b1(t), b2(t)). More precise westudy the saturation with the new class to the horizontal asymptote with respect tothe Hausdorff distance. Some numerical examples, using CAS MATHEMATICA arealso given. Studies in this paper can also be applied to a random shifted sigmoidalfunctions of generalized Gompertz–G families.
