update.BiBMA | R Documentation |
update.BiBMA
can be used to
add an additional model to an existing "BiBMA"
object by
specifying either a null or alternative prior for each parameter
and the prior odds of the model (prior_weights
), see the
vignette("CustomEnsembles")
vignette,
change the prior odds of fitted models by specifying a vector
prior_weights
of the same length as the fitted models,
refitting models that failed to converge with updated settings of control parameters,
or changing the convergence criteria and recalculating the ensemble
results by specifying new control
argument and setting
refit_failed == FALSE
.
