ipwCoxCSV-package       Inference of Marginal Hazard Ratios (HR) in
                        Inverse Probability Weighted (IPW) Cox Model
                        Using Corrected Sandwich Variance (CSV)
ipwCoxCluster           Inference of marginal HR in IPW Cox model based
                        on CSV with clustering
ipwCoxInd               Inference of marginal HR in IPW Cox model based
