DEmpiricalList

class DEmpiricalList<T>(elements: List<T>, theCDF: DoubleArray, stream: RNStreamIfc = KSLRandom.nextRNStream()) : RElementIfc<T>

Randomly selects the elements in the list according to a supplied CDF across the items

Parameters

the type of elements in the list
elements

the list of elements, must not be null

theCDF

an array holding the cumulative probabilities across the elements in the list

stream

the underlying random number stream to use for randomness

Functions

open override fun advanceToNextSubStream()

Positions the RNG at the beginning of its next substream

open override fun resetStartStream()

The resetStartStream method will position the RNG at the beginning of its stream. This is the same location in the stream as assigned when the RNG was created and initialized.

Link copied to clipboard
open override fun resetStartSubStream()

Resets the position of the RNG at the start of the current substream

open fun sample(): T

Returns an element randomly selected from the list

open fun sample(size: Int): List<T>

Returns sample of size from the list

open fun useStreamNumber(streamNumber: Int)

Assigns the stream associated with the supplied number from the default RNStreamProvider
