Class NormalEstimator

    • Constructor Detail

      • NormalEstimator

        public NormalEstimator​(double precision)
        Constructor that takes a precision argument.
        Parameters:
        precision - the precision to which numeric values are given. For example, if the precision is stated to be 0.1, the values in the interval (0.25,0.35] are all treated as 0.3.
