The European Community and the third world

For quite some time, and with Increasing commitment, people in the member states of the European Community have been discussing the question which role the Community should play in future as regards the developing countries in Africa, Asla and Latin America. From numerous quarters, the view is being voiced with mounting urgency that Europe should contribute more intensively towards solving the manifoid problems of the Third World.     

The UMVUE ofP(X<Y) based on type-II censored samples from Weinman multivariate exponential distributions

Based on two independent samples from Weinman multivariate exponential distributions with unknown scale parameters, uniformly minimum variance unbiased estimators ofP(X<Y) are obtained for both, unknown and known common location parameter. The samples are permitted to be Type-II censored with possibly different numbers of observations. Since sampling from two-parameter exponential distributions is contained in the model as a particular case, known results for complete and censored samples are generalized. In the case of an unknown common location parameter with a certain restriction of the model, the UMVUE is shown to have a Gauss hypergeometric distribution, which is further examined. Moreover, explicit expressions for the variances of the estimators are derived and used to calculate the relative efficiency.
