Wishart distribution arises as the distribution of the sample covariance matrix for a sample from a multivariate normal distribution. Some marginal densities, derived by integration of the Wishart density function are obtained. Necessary and sufficient conditions for positive definiteness of a matrix are established, which give the bounds of the integration. *2000 Mathematics Subject Classification: 62H10.
