mbq, I would not contradict your points.
Though first sense 'correlation' could well be useless in many cases at least I know what it means.
The second sense is perfidious as it's virtually impossible to deny there's a 'correlation' between any two things since the term so poorly defined.
- mbq 13y agoNote that I am criticising the idea of "general" or "intuitive" correlation; actually useful correlation measures (like Pearson or Spearman) will be just always tied to some model of dependence. This way it cannot be directly tied to the obviously absolute dependence.
