Implementation of VOI methods for structural uncertainty.
- Structural EVPI (Expected Value of Perfect Information for Model Structure)
- Structural EVPPI (Expected Value of Partial Perfect Information for Model Structure)
Structural uncertainty refers to uncertainty about the fundamental form or components of the model itself (e.g., choice of parametric family for survival, inclusion/exclusion of certain pathways, alternative model paradigms like decision tree vs. Markov model vs. DES).
These methods are often more complex to implement generically as they require ways to define, sample from, and evaluate alternative model structures.
Functions
Section titled “Functions”- structural_evpi Calculate expected value of perfect information for model structure.
- structural_evppi Calculate structural EVPPI for a subset of model structures.
- structural_evpi_jit Calculate structural EVPI with JAX acceleration.
- structural_evppi_jit Calculate structural EVPPI with JAX acceleration.
- mock_evaluator1 Return a fixed two-strategy net benefit array for smoke testing.
- mock_evaluator2 Return another fixed two-strategy net benefit array for smoke testing.
