Method Detail

ndimensions_child

public int ndimensions_child()

Description copied from interface: ConditionalDistribution

Return the number of dimensions of the child variable.

---

ndimensions_parent

public int ndimensions_parent()

Description copied from interface: ConditionalDistribution

Return the number of dimensions of the parent variables. If there is more than one parent, this is the sum of the dimensions of the parent variables.

---

get_density

public Distribution get_density(double[] c)
                         throws java.lang.Exception

For a given value c of the parents, return a distribution which represents p(x|C=c). Executing get_density(c). p(x) will yield the same result as p(x,c).

---

p

public double p(double[] x,
                double[] c)
         throws java.lang.Exception

Compute the density at the point x.

---

random

public double[] random(double[] c)
                throws java.lang.Exception

Return an instance of a random variable from this distribution.

---

format_string

public java.lang.String format_string(java.lang.String leading_ws)
                               throws java.io.IOException

Create a description of this distribution model as a string. This method simply puts the classname into a string.
