bilistic models and its effect on geotechnical reliability. First, the copula theory is briefly Gumbel copulas. ta. best-fit m rmation Cr (AIC) [20] or Bayesian Information Criterion (BIC) [21] in the copula approach. Furthermore, sample statistics such as mean, sample standard deviation (SD) and sample Kendall rank correlation coefficient are used to determine the para of marginal distributions and copulas. Theoretically, the joint CDF or PDF determined by the copula approach is accurat
