ergm (version 3.8.0)

is.curved: Testing for curved exponential family

Description

These functions test whether an ERGM fit or formula is curved.

Usage

# S3 method for ergm
is.curved(object, ...)
# S3 method for formula
is.curved(object, 
                    response=NULL,
                    basis=NULL,
                    …)
# S3 method for ergm.model
is.curved(object, ...)
# S3 method for NULL
is.curved(object, ...)

Arguments

object

An ergm object or an ERGM formula.

response, basis

Name of the edge attribute whose value is to be modeled. See ergm.

…

Unused at this time.

Value

TRUE if the model fit or one implied by the formula is curved; FALSE otherwise.

Details

Curvature is checked by testing if all model parameters are canonical.
