Details

Columns p1, p2, p3 stand for pre-albumin, albumin, globulins respectively. These were collected from 3-week old white Pekin ducklings. Let $Y_1$ be proportional to the total milligrams of pre-albumin in the blood serum of a duckling. Similarly, let $Y_2$ and $Y_3$ be directly proportional to the same factor as $Y_1$ to the total milligrams respectively of albumin and globulins in its blood serum. The proportion of pre-albumin is given by $Y_1/(Y_1 + Y_2 + Y_3)$, and similarly for the others.
