    "abstract": "Main result of this paper is to derive the exact analytical expressions of\ninformation and covariance matrices for multivariate Burr III and logistic\ndistributions. These distributions arise as tractable parametric models in\nprice and income distributions, reliability, economics, populations growth and\nsurvival data. We showed that all the calculations can be obtained from one\nmain moment multi dimensional integral whose expression is obtained through\nsome particular change of variables. Indeed, we consider that this calculus\ntechnique for improper integral has its own importance in applied probability\ncalculus.",
