is.dyad.independent: Testing for dyad-independence

Description

These functions test whether an ERGM fit, a formula, or some other object represents a dyad-independent model.

The method for NULL always returns FALSE by convention.

Usage

is.dyad.independent(object, ...)
# S3 method for NULL
is.dyad.independent(object, ...)
# S3 method for formula
is.dyad.independent(object, response = NULL,
  basis = NULL, ...)
# S3 method for ergm_conlist
is.dyad.independent(object, object.obs = NULL,
  ...)
# S3 method for ergm
is.dyad.independent(object, ...)

Arguments

object

The object to be tested for dyadic independence.

…

Unused at this time.

response

Name of the edge attribute whose value is to be modeled in the valued ERGM framework. Defaults to NULL for simple presence or absence, modeled via a binary ERGM.

basis

See ergm.

object.obs

For the ergm_conlist method, the observed data constraint.

Value

TRUE if the model implied by the object is dyad-independent; FALSE otherwise.

Details

Dyad independence is determined by checking if all of the constituent parts of the object (formula, ergm terms, constraints, etc.) are flagged as dyad-independent.
