Correlated_variable

The Correlated_variable is an ordered progression of positions or values (most often a sequence of spatial locations) that the (dependent) Attribute is measured against. The Correlated_variable is metaphorically mapped onto the progression of time, and in the absence of this FE, changes in the number in the Setare simply measured against (forward-directional) time. Mushrooms and deep moss proliferate as you get deeper into the trail.
