Constructors

SketchResult

constructor(probabilities: DoubleArray, quantiles: DoubleArray, gamma: Double, totalWeights: Double, zeroCount: Double, positiveBins: Map<Int, Double>, negativeBins: Map<Int, Double>)(source)

Properties

gamma

val gamma: Double(source)

Multiplicative bin-boundary ratio (1 + relativeError) / (1 - relativeError).

negativeBins

val negativeBins: Map<Int, Double>(source)

Negative-side bin counts keyed by signed log-bucket index.

positiveBins

val positiveBins: Map<Int, Double>(source)

Positive-side bin counts keyed by signed log-bucket index.

probabilities

val probabilities: DoubleArray(source)

Probabilities at which quantiles are evaluated; parallel to quantiles.

quantiles

val quantiles: DoubleArray(source)

Estimated quantile values, parallel to probabilities.

totalWeights

val totalWeights: Double(source)

Cumulative observation weight folded in.

zeroCount

val zeroCount: Double(source)

Weight observed at the zero bin.
