The Hermans-Rasson test as a powerful alternative to the Rayleigh test for circular statistics in biology.
Lukas LandlerGraeme D RuxtonErich Pascal MalkemperPublished in: BMC ecology (2019)
We recommend researchers switch to routine use of the new Hermans and Rasson test. We also demonstrate that all available tests have low power to detect departures from uniformity involving more than two concentrated regions: we recommend that where researchers suspect such complex departures that they collect substantially-sized samples and apply another recent test due to Pycke that was designed specifically for such complex cases. We provide clear textual descriptions of how to implement each of these recommended tests and encode them in R functions that we provide.
