glance.ergm {broom}

Glance at a(n) ergm object

Description

Glance accepts a model object and returns a tibble::tibble() with exactly one row of model summaries. The summaries are typically goodness of fit measures, p-values for hypothesis tests on residuals, or model convergence information.

Glance never returns information from the original call to the modeling function. This includes the name of the modeling function or any arguments passed to the modeling function.

Glance does not calculate summary measures. Rather, it farms out these computations to appropriate methods and gathers the results together. Sometimes a goodness of fit measure will be undefined. In these cases the measure will be reported as NA.

Glance returns the same number of columns regardless of whether the model matrix is rank-deficient or not. If so, entries in columns that no longer have a well-defined value are filled in with an NA of the appropriate type.

Usage

## S3 method for class 'ergm'
glance(x, deviance = FALSE, mcmc = FALSE, ...)

Arguments

x

An ergm object returned from a call to ergm::ergm().

deviance

Logical indicating whether or not to report null and residual deviance for the model, as well as degrees of freedom. Defaults to FALSE.

mcmc

Logical indicating whether or not to report MCMC interval, burn-in and sample size used to estimate the model. Defaults to FALSE.

...

Additional arguments to pass to ergm::summary(). Cautionary note: Misspecified arguments may be silently ignored.

Value

glance.ergm returns a one-row tibble with the columns

independence

Whether the model assumed dyadic independence

iterations

The number of MCMLE iterations performed before convergence

logLik

If applicable, the log-likelihood associated with the model

AIC

The Akaike Information Criterion

BIC

The Bayesian Information Criterion

If deviance = TRUE, and if the model supports it, the tibble will also contain the columns

null.deviance

The null deviance of the model

df.null

The degrees of freedom of the null deviance

residual.deviance

The residual deviance of the model

df.residual

The degrees of freedom of the residual deviance
