bbcdPar function

Representing Bayesian Biased Coin Design

Represents the randomization procedure Bayesian Biased Coin Design.

bbcdPar(N, a, groups = LETTERS[1:2])

Arguments

• N: integer for the total sample size of the trial.
• a: nonnegative parameter which controls the degree of randomness: For decreasing a the allocations become deterministic, while for increasing a the randomization procedure tends to complete randomization.
• groups: character vector of labels for the different treatments.

Returns

S4 object of the class bbcdPar.

Details

Extension of Efron's biased coin design.
