摘要翻译:
研究了具有预先规定边际的相关随机变量的联合概率分布的确定问题。当满足所有要求条件的联合分布不唯一时,“最无偏”选择对应于最大熵分布。最大熵分布的计算需要求解相当复杂的非线性耦合积分方程,对于高斯边值问题,得到了精确解;否则,如果存在边缘矩,解可以表示为围绕边缘乘积的扰动。

英文摘要:
The problem of determining the joint probability distributions for correlated random variables with pre-specified marginals is considered. When the joint distribution satisfying all the required conditions is not unique, the "most unbiased" choice corresponds to the distribution of maximum entropy. The calculation of the maximum entropy distribution requires the solution of rather complicated nonlinear coupled integral equations, exact solutions to which are obtained for the case of Gaussian marginals; otherwise, the solution can be expressed as a perturbation around the product of the marginals if the marginal moments exist.
