StoppingTargetProb

StoppingTargetProb is the class for stopping based on the probability of the DLT rate being in the target toxicity interval.

Usage

StoppingTargetProb(
  target = c(0.2, 0.35),
  prob = 0.4,
  report_label = NA_character_
)

.DefaultStoppingTargetProb()

Arguments

target

(number)
see slot definition.

prob

(proportion)
see slot definition.

report_label

(string or NA)
see slot definition.

Slots

target

(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.

Note

Typically, end users will not use the .DefaultStoppingTargetProb() function.

Examples

# 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)
