Table 3:

Sample means and standard deviations for Volterra (V) and Dabrowska (D) estimators of the bivariate survival function under a Clayton–Oakes model (9) with γ = 0 with unit exponential marginal distributions and dependency parameter θ. Censoring times were also exponentially distributed and independent of each other with censoring rate c taking values 0 (no censoring), 2 (moderate censoring), or 5 (heavy censoring) at various sample sizes (n), based on 1000 simulations at each configuration
