canberra_stability {OmicsMarkeR} | R Documentation |
Calculates canberra stability between two ranked lists. In brief, the raw canberra distance is scaled to a [0,1] distribution by the maximum canberra metric. Lastly, this value is subtracted from 1 to provide the same interpretation as the other stability metrics whereby 1 is identical and 0 is no stability.
canberra_stability(x, y)
x |
numeric vector of ranks |
y |
numeric vector of ranks with compatible length to x |
Returns the canberra stability for the two vectors
