The authors of the paper "Predicting Yolk Height, Yolk Width, Albumen Length, Eggshell Weight, Egg Shape Index, Eggshell Thickness, Egg Surface Area of Japanese Quails Using Various Egg Traits as Regressors"t used a multiple regression model with two independent variables where
y = quail egg weight (g),
X, = egg width (mm), and
X2
= egg length (mm).
The regression function suggested in the paper is -21.658 + 0.828x,
0.373x2.
