get_gof: Extract goodness-of-fit statistics a tidy format.

In modelsummary: Summary Tables and Plots for Statistical Models and Data: Beautiful, Customizable, and Publication-Ready

Extract goodness-of-fit statistics a tidy format.

Description

A unified approach to extract results from a wide variety of models.

Usage

get_gof(model, gof_function = NULL, vcov_type = NULL, ...)

Arguments

model	a single model object
gof_function	function which accepts a model object in the model argument and returns a 1-row data.frame with one custom goodness-of-fit statistic per column.
vcov_type	string vcov type to add at the bottom of the table
...	all other arguments are passed through to three functions. See the documentation of these functions for lists of available arguments. parameters::model_parameters extracts parameter estimates. Available arguments depend on model type, but include: standardize, include_reference, centrality, dispersion, test, ci_method, prior, diagnostic, rope_range, power, cluster, etc. performance::model_performance extracts goodness-of-fit statistics. Available arguments depend on model type, but include: metrics, estimator, etc. tinytable::tt, kableExtra::kbl or gt::gt draw tables, depending on the value of the output argument. For example, by default modelsummary creates tables with tinytable::tt, which accepts a width and theme arguments.

Value

A dataframe with the goodness-o-fit statistics. The backend attribute indicates the backend used to extract them. Moreover, for some models get_gof attaches useful attributes to the output. You can access this information by calling the attributes function attributes(get_estimates(model)).
