deal (version 1.1-1)

conditional: Calculate conditional distribution

Description

From master distribution the conditional distribution of a node given the parents is calculated.

Usage

conditional.cont(A,mu,nu,rho,phi) 
conditional(A,master,nw) 
conditional.disc(A,master) 
cond.node(node,nw,nw.prior=jointprior(nw))

Arguments

nw

The network.

node

The current node.

nw.prior

A joint prior, see jointprior.

A

The index of the current node.

master

Local master.

mu

Mu parameter in local master.

nu

Nu parameter in local master.

rho

Rho parameter in local master.

phi

Phi parameter in local master.

Value

• The node is updated with condprior attribute.

Details

Used in learn, which calls cond.node. The local master is calculated and sent to conditional which calls either conditional.cont or conditional.disc depending on the type of the node. In each case the localmaster is used for calculating the conditional distribution of the current node given the remaining nodes in the local master.
