Represents the randomization procedure Big Stick Design.
bsdPar(N, mti, groups = LETTERS[1:2])
S4
object of the class bsdPar
.
integer for the total sample size of the trial.
maximum tolerated imbalance in patient numbers during the trial.
character vector of labels for the different treatments.
Tossing a fair coin as long as the difference in group sizes does not
exceed the mti
. If the mti
is reached a deterministic
allocation is done, so that the difference in group sizes is reduced.
