Get an object to fit the BOIN model using the BOIN package.

get_boin(num_doses, target, use_stopping_rule = TRUE, ...)

Arguments

num_doses

Number of doses under investigation.

target

We seek a dose with this probability of toxicity.

use_stopping_rule

TRUE to use the toxicity stopping rule described in Yan et al. (2019). FALSE to suppress the authors' stopping rule, with the assumption being that you will test the necessity to stop early in some other way.

...

Extra args are passed to get.boundary.

Value

an object of type selector_factory that can fit the BOIN model to outcomes.
