Representing Generalized Biased Coin Design

Description

Represents the randomization procedure Generalized Biased Coin Design.

Usage

gbcdPar(N, rho, groups = LETTERS[1:2])

Arguments

N	integer for the total sample size of the trial.
rho	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.
groups	character vector of labels for the different treatments.

Details

Generalization of Wei's urn and Efron's biased coin design.

Value

S4 object of the class gbcdPar.
