Research ArticleOpen accessIn the abstractAn Assessment of Farmers Willingness to Pay for Wheat Consultant Engineers Project: In IranAli Asadi, Morteza Akbari, Hossain Shabanali Fami, Amir AlambaigiProblem statement: Public extension performance in many developing countries including Iran is not up to the expectation of farming community. Further, in recent years, many governments are very reluctant to shoulder huge financial investment for public extension. Hence, extension specialists and policy makers propose privatization of extension services in developing countries. Approach: Considering existing agricultural extension scenario, a study designed … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,405 accessesView PDF Cite

Research ArticleOpen accessIn the abstractKernel Density Estimation for Interdeparture Time of GI/G/1 QueuesHsing Luh, Berlin WuThe departure process of a single queue has been studied since the 1960s. Due to its inherent complexity, closed form solutions for the distribution of the departure process are nearly intractable. In this study, kernel type estimators of the density of interdeparture time in a GI/G/1 queue are studied. Uniform strong consistency of the estimators in a GI/G/1 queue and … …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,585 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordOn Concomitants of Ordered Ranked Set Sampling from Morgenstern FamilyMohammed S. KotbThis paper develops the distribution theory of concomitants in the context of ordered ranked set sample from the Farlie-Gumbel-Morgenstern bivariate family. Here, we derive the joint distribution of concomitants of two ordered ranked set sample and obtain their single and product moments alongside the correlation coefficient. Finally, an application of the results in establishing the moments and the variance-covariance for … …Journal of Mathematics and Statistics, Vol. 13, Issue 4 · 27 Dec 2017 · 6,965 accessesView PDF Cite
