These functions get information and data from regression models.

get_offset_name(model)

get_weights(model, data)

get_data(model, warn = TRUE)

get_response_name(model)

Arguments

model

The model (e.g., lm, glm, merMod, svyglm)

data

For get_weights, the data used to fit the model.

warn

For get_data, should there be a warning when model.frame won't work because of variable transformations? Default is TRUE but this may not be desired when get_data is used inside of another function or used multiple times.

Value

  • get_data(): The data used to fit the model.

  • get_response(): The name of the response variable.

  • get_offset_name(): The name of the offset variable.

  • get_weights(): A list with weights_name, the name of the weighting variable, and weights, the weights themselves (or all 1 when there are no weights).
