Cognitive-diagnosis model with process indicators — fit_cognitive_diagnosis

Uses GDINA for the response layer when available and retains process features as a parallel diagnostic channel. Process/mastery associations are reported descriptively and do not redefine the Q-matrix or skill labels.

Usage

fit_cognitive_diagnosis_process(
  response_matrix,
  q_matrix,
  process_data = NULL,
  process_features = NULL,
  person_id = NULL,
  engine = c("GDINA", "external"),
  external_engine = NULL,
  ...
)

Arguments

response_matrix: Person-by-item response matrix.
q_matrix: Q-matrix for cognitive-diagnosis modeling.
process_data: Process-data input used by the model.
process_features: Names of process-derived features.
person_id: Person or participant identifier.
engine: Estimation engine.
external_engine: Validated external fitting function.
...: Additional arguments passed to the selected model, engine, or method.
