Oriana, Circular Statistics for Windows, ver. 2

Oriana for Windows calculates the special forms of sample and inter-sample statistics required for circular data (e.g. angles measured in degrees, time of day, day of week, month of year, etc.).

The analyses include basic statistics such as mean vector and confidence limits, single sample distribution tests like Rayleigh's, pairwise and multisample tests such as Watson-Williams F-Test and chi-squared test, and pairwise correlations. It also graphs your data in a variety of ways, including rose diagrams, allowing you to easily demonstrate patterns.
