Graphical Model 5-Dim Binary Example Data

Description

This data set contains a matrix containing information on five binary variables (coded as 0/1) and the corresonding DAG model.

Usage

data(gmB)

Format

The format is a list of two components

x:

Int [1:5000, 1:5] 0 1 1 0 0 1 1 0 1 1 ...

g:

Formal class 'graphNEL' [package "graph"] with 6 slots
.. ..@ nodes : chr [1:5] "1" "2" "3" "4" ...
.. ..@ edgeL :List of 5
........

Details

The data was generated using Tetrad in the following way. A random DAG on five nodes was generated; binary variables were assigned to each node; then conditional probability tables corresponding to the structure of the generated DAG were constructed. Finally, 5000 samples were drawn using the conditional probability tables.

Examples

data(gmB)
## maybe str(gmB) ; plot(gmB) ...
