ContinuousDistribution

public ContinuousDistribution()

Method Detail

isDiscrete

public final boolean isDiscrete()

Specified by:

isDiscrete in interface Distribution

isContinuous

public final boolean isContinuous()

Specified by:

isContinuous in interface Distribution

getProbability

public abstract double getProbability(double x)

Description copied from interface: Distribution

This method returns the density of the given distribution at the specified value.

Specified by:

getProbability in interface Distribution

Parameters:

x - the value which density shall be returned

getLowerBound

public abstract double getLowerBound()

This method returns a lower bound of values. This bound should be given by the distributions tail, for example bounds should contain 95% interval. Nominal distributions should return NaN.

getUpperBound

public abstract double getUpperBound()

This method returns an upper bound of possible values. This bound should be given by the distributions tail, for example bounds should contain 95% interval. Nominal distributions should return NaN.

mapValue

public java.lang.String mapValue(double value)

Description copied from interface: Distribution

this method should return a string representation of the given value. Numerical Attributes might return a string representation of the value.

Specified by:

mapValue in interface Distribution
