Tidy summarizes information about the components of a model. A model component might be a single term in a regression, a single hypothesis, a cluster, or a class. Exactly what tidy considers to be a model component varies across models but is usually self-evident. If a model has several distinct types of components, you will need to specify which components to return.

# S3 method for svyolr
  conf.int = FALSE,
  conf.level = 0.95,
  exponentiate = FALSE,
  p.values = FALSE,



A svyolr object returned from survey::svyolr().


Logical indicating whether or not to include a confidence interval in the tidied output. Defaults to FALSE.


The confidence level to use for the confidence interval if conf.int = TRUE. Must be strictly greater than 0 and less than 1. Defaults to 0.95, which corresponds to a 95 percent confidence interval.


Logical indicating whether or not to exponentiate the the coefficient estimates. This is typical for logistic and multinomial regressions, but a bad idea if there is no log or logit link. Defaults to FALSE.


Logical. Should p-values be returned, based on chi-squared tests from MASS::dropterm(). Defaults to FALSE.


Additional arguments. Not used. Needed to match generic signature only. Cautionary note: Misspelled arguments will be absorbed in ..., where they will be ignored. If the misspelled argument has a default value, the default value will be used. For example, if you pass conf.lvel = 0.9, all computation will proceed using conf.level = 0.95. Additionally, if you pass newdata = my_tibble to an augment() method that does not accept a newdata argument, it will use the default value for the data argument.


In broom 0.7.0 the coefficient_type column was renamed to coef.type, and the contents were changed as well. Now the contents are coefficient and scale, rather than coefficient and zeta.

Calculating p.values with the dropterm() function is the approach suggested by the MASS package author https://r.789695.n4.nabble.com/p-values-of-plor-td4668100.html. This approach is computationally intensive so that p.values are only returned if requested explicitly. Additionally, it only works for models containing no variables with more than two categories. If this condition is not met, a message is shown and NA is returned instead of p-values.
