Very roughly, you're solving equations equal to the number of data columns that the TUI shows when running, or number of curves on the residual plot. However, each of those equations are made up of many terms.

Number of terms/variables will then come down to solved equations, sub models etc. You'd need to go through every setting, find the equations and then add up all of the terms. But some terms may be a constant, a single value for the whole model, vary with each cell, vary multiple times in an iteration etc. I have no idea how you'd find that number.

What do you want to do with the data? Ie what will you do with it?
