defines_mod: Check if the standard imset for a graph defines the model

In rje42/imset: Methods for imsets with mixed graphs

Check if the standard imset for a graph defines the model

Description

Check if the standard imset for a graph defines the model

Usage

defines_mod(
  graph,
  u,
  timeout = 60L,
  trace = FALSE,
  sparse = FALSE,
  rmv_edges = FALSE,
  stop_if_fail = TRUE
)

Arguments

graph	an ADMG in the form of a mixedgraph object
u	optionally, an imset to test the constraints from the graph on (otherwise the 'standard' imset is used)
timeout	an integer giving the maximum run time for each linear program in seconds
trace	logical: should details be given of tests?
sparse	logical: use sparse matrix?
rmv_edges	logical: only use missing edges in the graph in the constraint matrix?
stop_if_fail	logical: should procedure stop if one independence is not represeneted?

Details

The timeout argument requires version 5.6.13.4.9000 of lpSolve to be installed. If the function returns NA then no independence was found to be not in the model but at least one of the linear programs timed out.
