Grade model evidence against an explicit validation contract

Source: R/052-irt-validation-0-7.R
grade_model_evidence.Rd

This is intentionally conservative: failure of any required criterion caps the evidence grade. It does not convert exploratory evidence into a claim of substantive validity.

Usage

grade_model_evidence(
  recovery,
  spec = irt_validation_spec("unspecified"),
  external_validation = NULL,
  sbc = NULL,
  ppc = NULL,
  semantic_roundtrip = NULL
)

Arguments

recovery

Value supplied to `recovery`; see Details for its model-specific role.

spec

IRT model or validation specification.

external_validation

Value supplied to `external_validation`; see Details for its model-specific role.

sbc

Value supplied to `sbc`; see Details for its model-specific role.

ppc

Value supplied to `ppc`; see Details for its model-specific role.

semantic_roundtrip

Value supplied to `semantic_roundtrip`; see Details for its model-specific role.

Value

An object of class "eye_irt_evidence_grade", stored as a named list, with components "model_id", "grade", "checks", "recovery", "contract", "warning". It contains grade model evidence against an explicit validation contract and associated metadata or diagnostics needed to interpret the result.
