Identifiability plot of converged model for the simulation study 1 for \({\varphi }_{0}^{DSopen}\); \({\varphi }_{0}^{DS}\); \({\sigma }_{ 0}\); \(\beta\); \({\beta }_{0}\) and their associated linear regression (dotted red line) R2 values. Accurate parameter identification is represented by a dotted blue line. The \({\beta }_{0}\) parameter is depicted as a histogram of estimated values, as we didn’t vary it across simulations. See appendix S4 for identifiability plots of the other generated parameters.
