New Version 4 of Oriana has now been released. Have a look at the new features.

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

"I was quite pleased to discover Oriana. ... Overall, it seems like Oriana would be a useful addition to the suite of data analysis programs I use." - M.R., California, USA

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, circular histograms or wind roses, allowing you to easily demonstrate patterns.

You can get more detailed information, download detailed information in a PDF format, or download a fully working demo version.
