Likehood-Based Statistics for Other Links for orm Fits

Olinks(
  object,
  links = c("logistic", "probit", "loglog", "cloglog"),
  dec = 3,
  gradtol = 0.001
)

Arguments

object: an object created by orm with x=TRUE, y=TRUE
links: a vector of links to consider other than the one used to get object
dec: number of digits to the right of the decimal place to round statistics to
gradtol: tolerance for convergence on the absolute gradient; see lrm.fit and orm.fit.

Value

data frame. The R2 column is from the last adjusted \(R^2\) computed by orm, which adjustes for the effective sample size and the number of betas.
