Command-line User Interface Using Shao's Method


A call to the user-interface function used to allocate patients to one of two treatments using Shao's method proposed by Shao J, Yu X, Zhong B (2010) <doi:10.1093/biomet/asq014>.


StrBCD.ui(path, folder = "StrBCD")



the path in which a folder used to storage variables will be created.


name of the folder. If default, a folder named "StrBCD" will be created.


See StrBCD.


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 StrBCD.ui.


This function provides a command-line interface and users should follow the prompts to enter data including covariates as well as levels for each covariate, biased probability p and the covariate profile of the new patient.
