Some Contribution to Circular Statistics

In many diverse fields, the measurements are directions. A biologist may be interested in the direction of flight of the bird or orientation of an animal while geologist may be measuring the direction of earth¿s magnetic field such directions may be in two or three dimensions. A set of such observations on the directions is referred to as ¿DIRECTIONAL DATA¿. In particular analysis pertaining to two dimensional data falls under the topic ¿CIRCULAR STATISTICS¿. The following are the fields where some applications of directional data play a vital role Neuro Science, Geography, Archaeology , Remote Sensing, Spatial Analysis, Plant Phenology, Time Series, Image Analysis, Geographic Positional Systems, Orthopedics, Political Science, Defence Application, Computer Vision and Pattern Recognition, Physics etc.,
