is.durational: Testing for duration dependent models

In tergm: Fit, Simulate and Diagnose Models for Network Evolution Based on Exponential-Family Random Graph Models

Testing for duration dependent models

Description

These functions test whether an ERGM is duration dependent or not.

The method for NULL always returns FALSE by convention.

Usage

is.durational(object, ...)

## S3 method for class ''NULL''
is.durational(object, ...)

## S3 method for class 'ergm_model'
is.durational(object, ...)

## S3 method for class 'ergm_state'
is.durational(object, ...)

## S3 method for class 'formula'
is.durational(object, response = NULL, basis = ergm.getnetwork(object), ...)

Arguments

object	An ERGM formula, ergm_model object, or ergm_state object.
...	Unused at this time.
response, basis	See ergm().

Value

TRUE if the ERGM terms in the model are duration dependent; FALSE otherwise.

Methods (by class)

• is.durational(ergm_model): Test if the ergm_model has duration-dependent terms, which call for lasttoggle data structures.

• is.durational(ergm_state): Test if the ergm_state has duration-dependent terms, which call for lasttoggle data structures.
