      • randp

         final static Matrix randp(DoubleArray P, Integer rows, Integer cols)

        Pick random values with relative probability.

        Returns integers in the range from 1 to PROB.size with a relative probability, so that the value X is present approximately (PROBX-1/sum(PROB)) times.

        All values of PROB should be equal to or larger than 0.

        Parameters:
        P - Probability vector (all values should be >= 0)
        rows - Number of rows for output matrix
        cols - Number of columns for output matrix (defaults to rows if not specified)
        Returns:

        Matrix of random integers with specified probabilities

      • randp

         final static Matrix randp(Matrix P, Integer rows, Integer cols)

        Pick random values with relative probability (Matrix version).

        Parameters:
        P - Probability matrix (flattened column-wise)
        rows - Number of rows for output matrix
        cols - Number of columns for output matrix (defaults to rows if not specified)
        Returns:

        Matrix of random integers with specified probabilities

      • randp

         final static Integer randp(DoubleArray P)

        Generate a single random sample with relative probability.

        Parameters:
        P - Probability vector
        Returns:

        Single random integer with specified probability

      • randp

         final static Integer randp(Matrix P)

        Generate a single random sample with relative probability (Matrix version).

        Parameters:
        P - Probability matrix
        Returns:

        Single random integer with specified probability
