The existence of optimal parameters of generalized logistic function

The estimation of optimal parameters in a mathematical model described by the generalized logistic function with saturation level $A$ and the asymmetry coefficient $Đgamma$ is a nonlinear least squares problem. In this paper we prove the existence of optimal parameters under considerably weaker conditions than those required in Š1Ć.
