StoppingTargetProb
StoppingTargetProb
is the class for stopping based on the probability of
the DLT rate being in the target toxicity interval.
StoppingTargetProb(
target = c(0.2, 0.35),
prob = 0.4,
report_label = NA_character_
)
.DefaultStoppingTargetProb()

(number
)
the target toxicity interval, e.g. c(0.2, 0.35)
.
prob
(proportion
)
required target toxicity probability (except 0 or 1)
for reaching sufficient precision.
Typically, end users will not use the .DefaultStoppingTargetProb()
function.
# As example, here is the rule for stopping the study if the posterior
# probability that [0.2 =< Prob(DLT | dose) <= 0.35] for the next best dose
# is above 0.5.
my_stopping <- StoppingTargetProb(target = c(0.2, 0.35), prob = 0.5)
