Representing Bayesian Biased Coin Design

Description

Represents the randomization procedure Bayesian Biased Coin Design.

Usage

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.

Details

Extension of Efron's biased coin design.

Value

S4 object of the class bbcdPar.
