A call to the user-interface function used to allocate patients to one of two treatments using Atkinson's \(D_A\)-optimal biased coin design proposed by Atkinson A C (1982) <Doi:10.2307/2335853>.
# S3 method for carseq
DoptBCD.ui(path, folder = "DoptBCD")the path in which a folder used to store variables will be created.
name of the folder. If it is the default, a folder named "DoptBCD" will be created.
It returns an object of class "carseq".
The function print is used to obtain results. The generic accessor functions assignment, covariate, cov_num, cov_profile and others extract various useful features of the value returned by that function.
