Feature Summary

StructuralIdentifiability.jl can assess local and global identifiability of ODE models. In addition to these straightforward identifiability queries on individual parameters, the package can distinguish between single- and multi-experiment identifiability.

Feature List

  • Local identifiability checks
  • Global identifiability checks
  • Assessment of identifiable functions of parameters and states
  • Model reparametrization (experimental)

External tutorials

A tutorial paper describes some of the functionality (identifiability assessment and finding identifiable functions) in the context of epidemiological modeling (tested with the version 0.5.15 of the package).
