The dimension of a graphical model refers to the number of variables or parameters that define its structure. In the context of saturated models, it typically indicates the maximum complexity or the highest degree of interaction among variables. Understanding the dimension requires context, as the term "model" can vary widely in meaning across different mathematical fields. Resources that explain specific types of modeling can clarify the use of terms like "dimension" and "saturated." Providing context is essential for accurate interpretation in discussions about graphical models.
