Bayesian Information Criterion (BIC)

Compute Bayesian information criterion (BIC) or Schwarz's Bayesian criterion (SBC) for possibly one or several objects.

# S3 method for cox_cure
BIC(object, ..., method = c("obs", "effective"))

# S3 method for cox_cure_uncer
BIC(object, ..., method = c("obs", "certain-event"))

Arguments

object	An object for a fitted model.
...	Other objects of the same class.
method	A character string specifying the method for computing the BIC values. Notice that this argument is placed after ... and thus must be specified as a named argument. The available options for cox_cure objects are "obs" for regular BIC based on the number of observations, and "effective" for using BIC based on the number of effective sample size for censored data (number of uncensored events) proposed by Volinsky and Raftery (2000). The available options for cox_cure_uncer objects are "obs" for regular BIC based on the number of observations, and "certain-event" for a variant of BIC based on the number of certain uncensored events. For objects of either class, the former method is used by default.
