public ContinuousVertex()

Method Detail

logProb

public final double logProb(T value)

Description copied from class: Vertex

This is the natural log of the probability at the supplied value. In the case of continuous vertices, this is actually the log of the density, which will differ from the probability by a constant.

Specified by:

logProb in class Vertex<T extends Tensor>

Parameters:

value - The supplied value.

Returns:

The natural log of the probability density at the supplied value

dLogProb

public java.util.Map<java.lang.Long,DoubleTensor> dLogProb(T value)

Description copied from class: Vertex

The partial derivatives of the natural log prob.

Specified by:

dLogProb in class Vertex<T extends Tensor>

Parameters:

value - at a given value

Returns:

the partial derivatives of the log density

logPdf

public abstract double logPdf(T value)

dLogPdf

public abstract java.util.Map<java.lang.Long,DoubleTensor> dLogPdf(T value)
