Sammanfattning
A composition is a vector of positive components summing to a constant.
We consider the problem of describing the correlation between two compo-
sitions. Using a bicompositional Dirichlet distribution, we calculate a joint
correlation coefficient, based on the concept of information gain, between two
compositions. Numerical values of the joint correlation coefficient are calcu-
lated for compositions of two and three components.
