"WebFeb 24, 2024 · Similarly to correlation, the output is in the range of [0,1], where 0 means no association and 1 is full association. (Unlike correlation, there are no negative values, as there’s no such thing as a negative association. Either there is, or there isn’t) Like correlation, Cramer’s V is symmetrical — it is insensitive to swapping x and y " - Cramer's v correlation in r
