CRAN Package BI: Generate James (1996) and Bang (2004) Blinding Indices to assess whether or not satisfactory blinding has been maintained in a randomized, controlled, clinical trial. These can be generated for trial subjects, research coordinators (RCs) and principal investigators (PIs), based upon standardized questionnaires that have been administered, to assess whether or not they can correctly guess to which treatment arm (e.g. placebo or treatment) subjects were assigned at randomization.
