Enum TiesStrategy

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<TiesStrategy>

    public enum TiesStrategy
    extends java.lang.Enum<TiesStrategy>
    Strategies for handling tied values in rank transformations.
    • SEQUENTIAL - Ties are assigned ranks in order of occurrence in the original array, for example (1,3,4,3) is ranked as (1,2,4,3)
    • MINIMUM - Tied values are assigned the minimum applicable rank, or the rank of the first occurrence. For example, (1,3,4,3) is ranked as (1,2,4,2)
    • MAXIMUM - Tied values are assigned the maximum applicable rank, or the rank of the last occurrence. For example, (1,3,4,3) is ranked as (1,3,4,3)
    • AVERAGE - Tied values are assigned the average of the applicable ranks. For example, (1,3,4,3) is ranked as (1,2.5,4,2.5)
    • RANDOM - Tied values are assigned a random integer rank from among the applicable values. The assigned rank will always be an integer, (inclusively) between the values returned by the MINIMUM and MAXIMUM strategies.

    • Method Detail

      • values

        public static TiesStrategy[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (TiesStrategy c : TiesStrategy.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static TiesStrategy valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
