Estimation and Structure of Bayesian Tests for the Scale and Loction Parameters in Multivaiate- t distrbution

This paper deals with two problems Bayesian estimation and hypothesis tests to the parameters of Multivaiate- t distrbution when the degrees of freedom of distribution is known with the (informative and non- informative) prior information. The results were applied on the neonatal birth scales data in Nineva Governorate for the year (2005).
