is.curved {ergm}

R Documentation

Testing for curved exponential family

Description

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

Usage

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

Details

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

Value

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