We adopt the position that three basic notions are sufficient to describe all statistical models.
- We choose a Statistical Unit which we will observe directly. Multiple observations of the same unit over time is called Longitudinal Research. Observations of a variety of Statistical Attributes is a common way of studying relationships among the attributes of a single unit.
- We may really be interested in a Statistical Ensemble (or set) of similar units rather than in any Statistical Unit per se. Survey Sampling offers an example of this type of application.
- Our interest may be focused on a Statistical Assembly where we examine functional subunits of the Statistical Unit. Physiology is an example in which we probe the organs which compose the unit. A common model for this type of research is the Stimulus Response Model.
