Algorithm for globally identifiable reparametrizations of ODEs

Sebastian Falkensteiner, Alexey Ovchinnikov, J. Rafael Sendra

Structural global parameter identifiability indicates whether one can determine a parameter's value in an ODE model from given inputs and outputs. If a given model has parameters f…
