stop_rule_d1classical: Generating a stopping rule function for EWOC classical model

In ewoc: Escalation with Overdose Control

Generating a stopping rule function for EWOC classical model

Description

Generating a stopping rule function for EWOC classical model

Usage

stop_rule_d1classical(step)

Arguments

step	an object from the class 'ewoc_d1classical'.

Details

The function is evaluated at each step of the trial. It can defined based on any information contained in the object step that is the output from one of the functions ewoc_d1classical.

Value

a logical character indicating if the trial should be stopped or not.
