General method to compute log-likelihood for ghype models.

General method to compute log-likelihood for ghype models.

Usage
logl(
  object,
  xi = NULL,
  omega = NULL,
  directed = NULL,
  selfloops = NULL,
  adj = NULL,
  multinomial = NULL,
  ...
)

# S3 method for ghype logl( object, xi = NULL, omega = NULL, directed = NULL, selfloops = NULL, adj = NULL, multinomial = NULL, ... )

# S3 method for matrix logl( object, xi = NULL, omega = NULL, directed = NULL, selfloops = NULL, adj = NULL, multinomial = NULL, ... )

Arguments
object

either an adjacency matrix or ghype model If a ghype model is passed, then `xi`, `omega`, `directed`, `selfloops` are ignored If an adjacency matrix is passed, then `adj` is ignored

xi

matrix, combinatorial matrix to build ghype model, considered only if object is an adjacency matrix

omega

matrix, propensity matrix to build ghype model, considered only if object is an adjacency matrix

directed

boolean, is ghype model directed? considered only if object is an adjacency matrix

selfloops

boolean, has ghype model selfloops? considered only if object is an adjacency matrix

adj

optional matrix, adjacency matrix of which to compute log-likelihood, cconsidered only if object is ghype model If adj is not passed, and object is a ghype model, the log-likelihood is computed for the original adjacency matrix stored in object.

multinomial

optional boolean. Force multinomial approximation? If not chosen, multinomial chosen for large graphs.

...

additional parameters passed to and from internal methods

Value

loglikelihood value
