Abstract:
Abstract- The method of parsimony in phylogenetic inference is often taken to mean two things: (1) that one should favor the genealogical hypothesis that minimizes the required number of homoplasies (matchings of independently evolved derived character states), and (2) that symplesiomorphies (matchings of primitive character states) have little or no evidential value for phylogenetic relationship. This paper shows both theses to be false by undermining recent likelihood arguments for them and by providing a more secure likelihood proof of a new method, which is incompatible with both (1) and (2).

Coefficient of Correlation
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
