Estimation-focused variance-reduction value of information.

This module is intentionally separate from decision-focused EVPPI and EVSI. Its public names describe reductions in uncertainty about a declared target, not expected changes in a decision’s net benefit.

Functions

Section titled “Functions”
  • estimation_variance_method Return the governed descriptor for an estimation-variance method.
  • evppi_var Estimate scalar variance reduction from perfect discrete conditioning.
  • evsi_var Aggregate scalar variance reduction across declared study outcomes.
