Add coefficients type and label as attributes

Add the type of coefficients ("generic", "logistic", "poisson", "relative_risk" or "prop_hazard") and the corresponding coefficient labels, as attributes to x (respectively named coefficients_type and coefficients_label).

Usage

tidy_add_coefficients_type(
  x,
  exponentiate = attr(x, "exponentiate"),
  model = tidy_get_model(x)
)

Arguments

x

(data.frame)
A tidy tibble as produced by tidy_*() functions.

exponentiate

(logical)
Whether or not to exponentiate the coefficient estimates. It should be consistent with the original call to broom::tidy().

model

(a model object, e.g. glm)
The corresponding model, if not attached to x.
