Abstract

The authors compare the results of several analytical identification methods adequacy of the Ferhulst (Pearl–Reed) logistic dynamics model by using test samples with different volumes, wide range of the model parameters values and stochastic component variances. The article shows the preference of using the Levenberg–Marquardt algorithm for minimizing a least squares method function for Ferhulst model and its possibility to model ‘fetish’-shaped product life cycles.
