Estimation of Edge in Population of Binary Tree Using Stratified Sampling Procedure
Abstract: Sampling methodologies is a tool to investigate about the information of unknown population parameters. Sometimes the population has the tree structure where one node has two or many paths to scatter. For example, from one airport, there are many routes to travel to different airports; and further, other airports have many similar links. This creates graphical structure of connectivity among different airports around the world. Now the problem of investigation …
