Represents the randomization procedure Bayesian Biased Coin Design.
bbcdPar(N, a, groups = LETTERS[1:2])integer for the total sample size of the trial.
nonnegative parameter which my be adjusted according to how strongly it is
desired to balance the experiment. a = 0 gives the complete randomization, while the
assignments become more deterministic as a increases.
character vector of labels for the different treatments.
S4 object of the class bbcdPar.
