Stratified.staged.tree

Description

A stratified staged tree is a staged tree whose supporting event tree is stratified and all vertices which are in the same stage are also at the same distance of edges from the root.

Slots

event.tree

Stratified.event.tree. An stratified event tree is an event tree whose set of events that unfold from all situations, which are at the same distance of edges from the initial situation, are identical.

situation

list.

contingency.table

list of matrices that represent the contigency tables associated with each variable in the event tree.

stage.structure

list in which each component is a list associated with a variable in the staged tree that has the following data structure:

• $score - numeric. This is the logarithmic form of the marginal likelihood associated with a particular variable.

• $cluster - list whose components are vectors. Each vector represents a stage associated with a particular variable.

stage.probability

list in which each component is a list associated with a variable in the staged tree. Each component of this sublist is a vector that represents the probability distribution associated with a particular stage of the target variable.

prior.distribution

list of matrices. Each matrix is a collection of vectors that correspond t a prior distribution for each situation associated with a particular variable.

posterior.distribution

list of matrices. Each matrix is a collection of vectors that correspond t a prior distribution for each situation associated with a particular variable.

model.score

numeric. This is the logarithmic form of the marginal likelihood.
