PriorDistribution

"Stratified.event.tree" a S4 object that represents an event tree.

stratified.event.tree

numeric It plays a role of a phantom sample to construct 
the prior probability distribution and reprssents 
the prior knowledge about the process.

alpha

<code>PriorDistribution</code> initialises the prior distributions under the
conservative and uniform assumptions for the hyperparameter 'alpha' over
the event tree.

Create and learn Chain Event Graph (CEG) models using a Bayesian
framework. It provides us with a Hierarchical Agglomerative algorithm to
search the CEG model space.
The package also includes several facilities for visualisations of the
objects associated with a CEG. The CEG class can represent a range of
relational data types, and supports arbitrary vertex, edge and graph
attributes. A Chain Event Graph is a tree-based graphical model that
provides a powerful graphical interface through which domain experts can
easily translate a process into sequences of observed events using plain
language. CEGs have been a useful class of graphical model especially to
capture context-specific conditional independences. References: Collazo R,
