The white paper says that the policies well fit the national conditions and are correct. They are instrumental to promoting harmonious coexistence of all nationalities that work with one heart and one mind and in mutual cooperation; they have helped open up a good national situation characterized by economic development, political stability,展开更多

The graphs are mixed graphs with possibly two kind of edges, namely directed and bidirected edges. The vertex set denotes random variables at dif- ferent times. In Gaussian case, the latent ancestral graph leads to a simple parameterization model. A modified iterative conditional fitting algorithm is presented to obtain maximum likelihood esti- mation of the parameters. Furthermore, a log-likelihood criterion is used to select the most appropriate models. Simulations are performed using illustrative examples and results are provided to demonstrate the validity of the methods.展开更多
