ABSTRACT
This quote comes from the book on model-building and response surfaces by Box and Draper [1987]. It is quoted often because it provides useful insights about the nature of building and using models. In many data analysis applications, we are interested in creating models to represent some observed phenomenon. Statisticians collect data and use these to create the models that hopefully capture the phenomenon. Models are just a representation of some real process and are likely based on our own ideas of reality. Thus, they are typically wrong and will have some error associated with them.
