Bases: object

Configuration influencing resolution and output generation.

Parameters:

• estimation_mode (EstimationMode) – Maximum likelihood or Bayesian mode.

• draw_type (str) – Draw type used for latent variables.

• positivity_mode (PositivityMode) – Positive-parameter parameterization.

• naming (NamingPolicy) – Naming policy.

• ordinal_eps (float) – Lower clipping bound for ordinal probabilities.

• ordinal_enforce_order (bool) – Whether to enforce ordered cutpoints.
