CCANone

CCANone is a term used within the CCA (Canonical Correspondence Analysis) framework, indicating the absence of a specific canonical axis or component in the analysis. In simpler terms, it signifies that no particular pattern or relationship has been identified or explained by that axis in the data set. It's like saying there's no meaningful gradient or connection captured along that dimension, often used to denote a null or non-significant result within the analysis. This helps researchers understand which components contribute meaningful information and which do not.
