D. Jukic et R. Scitovski, THE EXISTENCE OF OPTIMAL PARAMETERS OF THE GENERALIZED LOGISTIC FUNCTION, Applied mathematics and computation, 77(2-3), 1996, pp. 281-294
The estimation of optimal parameters in a mathematical model described
bg the generalized logistic function with saturation level A and the
asymmetry coefficient gamma is a nonlinear least squares problem. In t
his paper we prove the existence of optimal parameters under considera
bly weaker conditions than those required in [1].
