Class NaiveBayesClassifierEx3.TestGaussFcn1

java.lang.Object

com.imsl.test.example.datamining.NaiveBayesClassifierEx3.TestGaussFcn1

All Implemented Interfaces:

Distribution, ProbabilityDistribution, Serializable

Enclosing class:

NaiveBayesClassifierEx3

public static class NaiveBayesClassifierEx3.TestGaussFcn1
extends Object
implements ProbabilityDistribution

Defines the user supplied probability distribution.

In this case, the probability distribution is Gaussian and results should match the default case in Example 1.

Method Detail

eval

public double[] eval(double[] xData)

Description copied from interface: Distribution

Evaluation method to fit the user-supplied probability density function to input data

Specified by:

eval in interface Distribution

Parameters:

xData - a double array representing the points at which the probability density function is to be evaluated.

Returns:

a double array representing the probability density at each value of xData

eval

public double[] eval(double[] xData,
                     Object[] Params)

Description copied from interface: ProbabilityDistribution

Evaluates the user-supplied probability density of each value in xData using the supplied probability distribution parameters.

Specified by:

eval in interface ProbabilityDistribution

Parameters:

xData - a double array containing the points at which the probability density function is to be evaluated

Params - an Object array containing the probability distribution parameters to be used in evaluating xData, see method getParameters

Returns:

a double array representing the probability density of each value in xData

eval

public double eval(double xData,
                   Object[] Params)

Description copied from interface: ProbabilityDistribution

Evaluation method for the user-supplied distribution function and parameters. Evaluates the user-supplied probability density at xData using the supplied probability distribution parameters.

Specified by:

eval in interface ProbabilityDistribution

Parameters:

xData - a double scalar value containing the point the distribution function is to evaluate

Params - an Object array containing the probability distribution parameters to be used in evaluating xData. See method getParameters.

Returns:

a double scalar value representing the probability density at xData

getParameters

public Object[] getParameters()

Description copied from interface: ProbabilityDistribution

Returns the current parameters of the probability density function.

Specified by:

getParameters in interface ProbabilityDistribution

Returns:

an Object array containing the parameters resulting from the last invocation of the (Distribution) eval method with the following signature, double[] eval(double[] xData). This Object array can be used as input to the eval methods that require an Object array of distribution parameters as input.
