What is a parameter regression in modeling?
That terminology is not specific enough to identify a particular technique in mathematics. If you saw it mentioned in some context, you should explain the situation.
It was used in the context of using engineering models/correlations based on experimental data: After obtaining an analytically derived mathematical model for a simpler system to use the regressed parameters to make more accurate predictions for more complex systems.
I tried googling it but in vain:(
They mean exactly what they said: do regression and then use the model to make predictions for a more complex system. Wikipedia has a good article on regression.
