  • Field Details

  • Constructor Details

    • Det

      public Det(double t)
      Creates a deterministic distribution with the specified constant value.
      Parameters:
      t - the constant value for this deterministic distribution

  • Method Details

    • fitMean

      public static Det fitMean(double mean)
      Creates a deterministic distribution with the specified mean value. This is equivalent to new Det(mean).
      Parameters:
      mean - the mean value for the deterministic distribution
      Returns:
      a new Det distribution with the specified mean

    • evalCDF

      public double evalCDF(double t)
      Evaluates the cumulative distribution function at the given point. Returns 0 if t < value, 1 if t >= value.
      Specified by:
      evalCDF in class Distribution
      Parameters:
      t - the point at which to evaluate the CDF
      Returns:
      0 or 1 depending on whether t has reached the deterministic value

    • evalLST

      public double evalLST(double s)
      Evaluates the Laplace-Stieltjes transform at the given point.
      Specified by:
      evalLST in class Distribution

      public org.apache.commons.math3.complex.Complex evalLST(org.apache.commons.math3.complex.Complex s)
      The transform at a COMPLEX argument, exp(-s d), exact and analytic. The CDF sum of Distribution.evalLST(org.apache.commons.math3.complex.Complex) cannot see this law at all: its measure is a single atom, which no grid of increments resolves.
      Overrides:
