Outline of Final Research Achievements

Directional data arise when one or more of the variables being observed is angular, and occur in fields as diverse as astronomy, ecology, medicine and the environmental sciences. Examples include the fallen tree directions and the directions of wind. Such a study is called Directional Statistics.
For a statistical modeling of the directional data, we have developed some statistical models for circular data and investigated their properties. In addition, we have given an index for the prosperity of the forest focusing on the fallen trees directions.
