model_get_model_matrix {broom.helpers}

Get the model matrix of a model

Description

The structure of the object returned by stats::model.matrix() could slightly differ for certain types of models. model_get_model_matrix() will always return an object with the same structure as stats::model.matrix.default().

Usage

model_get_model_matrix(model, ...)

## Default S3 method:
model_get_model_matrix(model, ...)

## S3 method for class 'multinom'
model_get_model_matrix(model, ...)

## S3 method for class 'clm'
model_get_model_matrix(model, ...)

## S3 method for class 'brmsfit'
model_get_model_matrix(model, ...)

## S3 method for class 'glmmTMB'
model_get_model_matrix(model, ...)

## S3 method for class 'plm'
model_get_model_matrix(model, ...)

## S3 method for class 'biglm'
model_get_model_matrix(model, ...)

## S3 method for class 'model_fit'
model_get_model_matrix(model, ...)

## S3 method for class 'fixest'
model_get_model_matrix(model, ...)

## S3 method for class 'LORgee'
model_get_model_matrix(model, ...)

## S3 method for class 'betareg'
model_get_model_matrix(model, ...)

## S3 method for class 'cch'
model_get_model_matrix(model, ...)

## S3 method for class 'cch'
model_get_terms(model, ...)

Arguments

model

a model object

...

additional arguments passed to stats::model.matrix()

Details

For models fitted with glmmTMB::glmmTMB(), it will return a model matrix taking into account all components ("cond", "zi" and "disp"). For a more restricted model matrix, please refer to glmmTMB::model.matrix.glmmTMB().

For plm::plm() models, constant columns are not removed.
