Empirical vs. Conceptual Model

Often times, we need to choose between the conceptual modeling framework and the empirical. We should consider the definition of each:


The empirical model

 
The empirical model attempts to establish a causal linkage between “X” and “Y” without detailed consideration of the internal processes. The equations and parameters of such model have limited physical significance. Instead, they are selected through optimization of some goodness-of-fit criterion.


The conceptual model

 
The conceptual model represents, to the extent possible, all physical mechanisms that govern the process within the system.

  2. I'm currently reading an article that says it uses an "empirical conceptual model." How does one combine the two models for qualitative research?
