The overarching objective of this project is to explore and analyze the various impacts of D-penicillamine (DPCA) treatment compared to placebo during the clinical trial for patients with Primary Biliary Cirrhosis (PBC). The authentic data stems from a meticulously conducted double-blinded randomized trial by the Mayo Clinic between January 1974 and May 1984. The data encompasses an exhaustive range of variables, including clinical, biochemical, serologic, and histologic parameters for each enrolled subject. It's pivotal to note that while the actual Mayo Clinic trial involved 424 eligible patients, with 312 agreeing to partake in the randomized trial, the dataset you will utilize for this investigation is a simulated version and incorporates more participants (your results will not be publishable). A thorough explanation of the trial's clinical context and the covariates is documented in Fleming
