model_identify_variables: Identify for each coefficient of a model the corresponding variable

Description

It will also identify interaction terms and intercept(s).

Value

A tibble with four columns:

• term: coefficients of the model

• variable: the corresponding variable

• var_class: class of the variable (cf. stats::.MFclass())

• var_type: "continuous", "dichotomous" (categorical variable with 2 levels), "categorical" (categorical variable with 3 or more levels), "intercept" or "interaction"

• var_nlevels: number of original levels for categorical variables

Arguments

model

a model object
