Circular (directional) statistics is a branch of statistics that focuses on the analysis of directional (cyclic) data, that are usually shown as a circular chart that is divided into days, months or years. To be able to study this type of data with a computer it's necessary to use an application like Oriana.
The main objective of Oriana is to make it possible to analyze data so that it is easy to see the comparison between the data provided as time goes by.
By means of Oriana it will be possible to analyze a set of data or on the contrary carry out comparative analyses between two or more groups of data.
Oriana's interface is distributed so that it is very easy to access all the data and graphics with a simple movement of the mouse, making it easier for the user to view and understand the data.
Therefore, if you're looking for a tool that will help you in the analysis of directional data, you only have to download Oriana.
