RegressionTerminalLeaf

class RegressionTerminalLeaf(val arm: SeriesStat<WeightedVarianceResult>) : RegressionLeafNode(source)

Frozen leaf; no further splits will be considered.

Constructors

constructor(arm: SeriesStat<WeightedVarianceResult>)

Properties

arm

open override val arm: SeriesStat<WeightedVarianceResult>

The leaf's weighted-variance accumulator.

Functions

findLeaf

override fun findLeaf(row: VectorView): RegressionLeafNode

Walk to the leaf this row resolves to.

snapshot

fun RegressionNode.snapshot(): TreeNodeResult

Freeze a live tree node into an immutable snapshot. Internal split aggregates are derived from the snapshotted children so the wire format stays stable even though live splits hold no arm.
