Relative Frequencies of Serum Proteins in White Pekin Ducklings
Description
Relative frequencies of serum proteins in white Pekin ducklings
as determined by electrophoresis.
Usage
data(ducklings)
Format
The format is:
chr "ducklings"
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.
