 Author Comment/Response Koiy 05/13/03 4:12pm I would appreciate someone´s help with the following issue: I need to calculate the multinormal distribution showing in the code below << Statistics`MultinormalDistribution` CDF[MultinormalDistribution[{0, 0, 0, 0}, {{1., 0.62, 0.91, 0.62}, {0.62, 1., 0.58, 0.58}, {0.91, 0.58, 1., 0.55}, {0.62, 0.58, 0.55, 1.}}], {-3.57, -3.41, -4.24, -5.48}] But I obtain the error message: CDF::"mnormsig": "The parameter sigma in MultinormalDistribution[mu, sigma] \ does not have a structure allowing computation of \ CDF[MultinormalDistribution[mu, sigma], x]. Currently, the structure of \ sigma is restricted to {{s1^2, s1 s2 l1 l2, s1 s3 l1 l3, ...}, {s2 s1 \ l2 l1, s2^2, s2 s3 l2 l3, ...}, {s3 s1 l3 l1, s3 s2 l3 l2, s3^2, \ ...}, ...}, where Abs[li] <= 1, i = 1, 2, 3, ... ." What is the reason? Thanks URL: ,
