Testing for correlation between two directional or orientational variates. Assumes “large” number of observations. Requires two columns of directional (0-360) or orientational (0-180) data in degrees. For mathematical details, see the Past manual.
This module uses the circular correlation procedure and parametric significance test of Jammalamadaka & Sengupta (2001).
