FittingCatalog

object FittingCatalog(source)

Stable-ID registry of every parameter estimator, scoring model, and distribution family currently reachable from the fitting subsystem.

IDs are wire-safe (lowercase, hyphen-separated) and decouple serializable configurations and DTOs from KSL class names. Front-ends, CLIs, and agents enumerate capabilities through this catalog rather than through reflection.

Defaults mirror PDFModeler's own opinion exactly: defaultEstimatorIds for CONTINUOUS returns the union of PDFModeler.nonRestrictedEstimators and PDFModeler.positiveRestrictedEstimators; defaultScoringModelIds returns the IDs of PDFModeler.defaultScoringModels. Estimators and scoring models outside those defaults are still registered (and resolvable by ID) but opted into explicitly.

The discrete entries are listed for catalog completeness; the continuous-only fitting runner will reject them via the validator until the discrete (PMF) path lands.

Properties

val estimators: List<EstimatorDescriptor>

All registered estimators in catalog order.

val families: List<DistributionFamilyDescriptor>

All registered distribution families in catalog order.

val scoringModels: List<ScoringModelDescriptor>

All registered scoring models in catalog order.

Functions

defaultEstimatorIds

fun defaultEstimatorIds(kind: DistributionKind): Set<String>

Default estimator IDs for the given kind:

defaultScoringModelIds

fun defaultScoringModelIds(): Set<String>

Default scoring model IDs, mirroring PDFModeler.defaultScoringModels. Scoring is currently used only on the continuous path.

fun estimator(id: String): EstimatorDescriptor

Looks up an estimator descriptor by its catalog ID; throws when unknown.

estimatorOrNull

fun estimatorOrNull(id: String): EstimatorDescriptor?

Looks up an estimator descriptor by its catalog ID; null when unknown.

fun familyIdFor(rvType: RVParametersTypeIfc): String?

Maps an RVParametersTypeIfc back to its catalog family ID, or null when the type is not represented by any registered estimator.

fun familyOrNull(id: String): DistributionFamilyDescriptor?

Looks up a family descriptor by its catalog ID; null when unknown.

fun scoringModel(id: String): ScoringModelDescriptor

Looks up a scoring model descriptor by its catalog ID; throws when unknown.

scoringModelOrNull

fun scoringModelOrNull(id: String): ScoringModelDescriptor?

Looks up a scoring model descriptor by its catalog ID; null when unknown.
