摘要：A probabilistic graphical model of conditional bivariate copulas is presented in this paper. Variational inference is employed to estimate the parameters of the proposed model. A detailed calculation process is provided for the reproducible research. Experimental results on a simulated data set illustrate the effectiveness of the methodology.
