Represents the Truncated Binomial Design.
tbdPar(bc = N, groups = LETTERS[1:2])vector which contains the lengths k_1,...,k_l of each block.
This means that the vector bc will have one entry for each block.
character vector of labels for the different treatments.
S4 object of the class tbdPar.
A fair toin is tossed until half of the patients have been assigned to one of the treatment arms. Afterwards, the randomization list is filled with the other treatment.
