Constructor Detail

Interval

public Interval(int small,
                int tamanio)

Constructor

Parameters:

small - SMALL flag.

tamanio - size of the interval.

Method Detail

add

public void add(double dato)

Adds a new value to the interval.

Parameters:

dato - value to add.

setClass

public void setClass(int c,
                     int indice)

Sets a class that belong to the interval.

Parameters:

c - given class.

indice - index where to set it.

getNumValues

public int getNumValues()

Returns the number of values in it.

Returns:

number of values.

getOptimalClass

public int getOptimalClass()

Returns the optimal class.

Returns:

optimal class.

getValues

public double[] getValues()

Returns the values of the interval.

Returns:

the values of the interval.

clear

public void clear()

Clear the interval of values.

optimalClass

public int optimalClass(int numClases,
                        long seed,
                        boolean ultimoIntervalo)

Finds the optimal class for the interval. If there are not a class with more values than the threshold SMALL, it returns -1. But if it is the last interval, it returns the most frequent one.

Parameters:

numClases - number of classes.

seed - Seed for the random number generator.

ultimoIntervalo - Last interval flag.

Returns:

the optimal class for the interval.

print

public void print()

Prints on the standard output the interval.
