 Overview

 In the following, we demonstrate how to set up a parameter estimation
 problem in PEtab based on a realistic application example. To this end,
 we consider the model and experimental data by

 model describes the dynamics of phosphorylation and dimerization of the
 transcription factors STAT5A and STAT5B. A visualization and the
 corresponding reactions of the model are provided below, although the
 details of the model are not relevant for the purpose of this tutorial.
