Enum Constant Detail

MEAN

public static final ImputingStrategy MEAN

The default strategy. If this strategy is chosen, then replace missing values using the mean for the numeric features along the axis.

MOST_FREQUENT

public static final ImputingStrategy MOST_FREQUENT

If this strategy is chosen, then replace missing using the most frequent value along the axis.

Method Detail

values

public static ImputingStrategy[] 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 (ImputingStrategy c : ImputingStrategy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ImputingStrategy valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
