Represents the randomization procedure Generalized Biased Coin Design.
gbcdPar(N, rho, 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. If rho = 1
, we have Wei's urn design with
alpha = 0
. If rho = 0
, we have complete randomization.
character vector of labels for the different treatments.
