  +--nb.NBNorm

public class NBNorm

extends java.lang.Object

NBNorm is a helper class to hold the 3rd dimension of an Array2 containing the parameters of the Normal Density for each (continuous attribute,label) combination. The hd (hasData) argument defaults to FALSE.

Field Summary

boolean	hasData If true the data in this NBNorm is valid, if false there is no valid data stored in this object.
double	mean stores the mean value of the data.
double	var stores the variance of the data.

Constructor Summary

NBNorm()
This is the default constructor.

NBNorm(double m, double v, boolean hd)
This constructor sets fields to parameter values.

NBNorm(NBNorm rhs)
The copy constructor for NBNorm.

Method Summary

boolean	equals(NBNorm rhs) Equivalent to operator==.
void	set_mean_and_var(double m, double v) Sets the mean and variance.

Field Detail

mean

public double mean

stores the mean value of the data.

var

public double var

hasData

public boolean hasData

If true the data in this NBNorm is valid, if false there is no valid data stored in this object.

Constructor Detail

NBNorm

public NBNorm()

This is the default constructor. All fields set to default.

NBNorm

public NBNorm(double m,
              double v,
              boolean hd)

This constructor sets fields to parameter values.

Parameters:

m - - the mean value.

v - - the variance.

hd - - the has data boolean.

NBNorm

public NBNorm(NBNorm rhs)

The copy constructor for NBNorm.

Method Detail

set_mean_and_var

public void set_mean_and_var(double m,
                             double v)

Sets the mean and variance.

Parameters:

m - - the new mean.

v - - the new variance.

equals

public boolean equals(NBNorm rhs)

Equivalent to operator==. Provided for use by NaiveBayesCat.equals.

Parameters:

rhs - - the NBNorm to test equalitly.

Returns:

true if the this is equal to rhs; false else.
