A simple selection test between the Gompertz and Logistic growth models

•A simple selection test between the Gompertz and the Logistic curves is proposed.•The selection is based on the t-test of one parameter in a linear regression.•Simulations studies show that the test has acceptable size and power.•Applications to real data are provided.

This paper proposes a simple model selection test between the Gompertz and the Logistic growth models based on parameter significance testing in a comprehensive linear regression. Simulations studies are provided to show the accuracy of the method. Two real-data examples are also provided to illustrate the implementation of the proposed method in practice.
