R Documentation

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 class 'NULL'
is.dyad.independent(object, ...)

## S3 method for class 'formula'
is.dyad.independent(object, response = NULL,
  basis = NULL, ...)

## S3 method for class 'ergm_conlist'
is.dyad.independent(object, object.obs = NULL,
  ...)

## S3 method for class '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.

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.

Value

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