Random Cows, Random Corn, and Random Effects
Abstract
The modeling of random effects has followed different developments in
different areas of application. In particular, the definition of a
random effect used by an animal scientist can be different from the
random effect used by a plant scientist. This distinction was one that
intrigued Professor Myra Samuels. In this talk the different interpretations
of random effects are explained. In particular, the definitions of random
effects are related to the familiar statistical methodologies of mixed model
analysis and blocking designs. We will see that the different interpretations
of random effects have consequences on both the scope of the model and the
types of conclusions that are possible.
