Representing Truncated Binomal Design

Represents the Truncated Binomial Design.

tbdPar(bc = N, groups = LETTERS[1:2])

Arguments

• bc: 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.
• groups: character vector of labels for the different treatments.

Returns

S4 object of the class tbdPar.

Details

A fair coin 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.
