In 30 blood samples portions of three kinds of white cells
data(WhiteCells)
In an experiment each of 30 blood samples was halved, one half being assigned randomly to one method, the other half to the other method. We have 60 cases of 3-part compositions but these are essentially 30 pairs of related compositions. All 3-part portions sums to one, except for some rounding errors.
