Class MemorylessTruncatedWrapper

  • All Implemented Interfaces:
    java.io.Serializable, org.apache.commons.math3.analysis.UnivariateFunction, org.apache.commons.math3.distribution.RealDistribution
    public class MemorylessTruncatedWrapper
extends TruncatedWrapper
    When truncating an exponential function left (setting a lower constraint), the result is the same exponential function offset by the constraint

    exp(x,lambda=2) truncated with x>=3 is: exp(x | x >= 3, lamda=2) = exp(x-3, lamda=2)

      • sample

        public double sample()
        Description copied from class: TruncatedWrapper
        Slice sampling Note that due to floating point arithmetic, too large constraints, i.e. those where the density of the truncated distribution is 0, will not work!
        Specified by:
        sample in interface org.apache.commons.math3.distribution.RealDistribution
        Overrides:
        sample in class TruncatedWrapper
