Continuing with the new regression model. Now it's the discrete dataset.

And here's what the coefficients look like:

The most marked difference of this from the coefficients induced from the original dataset is that the second condition's behavior has changed, and is no longer so well compressed. There is a significant increase in number of states from the 2nd to the 3rd phase of the second condition, whereas this increase is non-significant between the same phases of the first condition.

So the discrete meanings reduced the efficiency of the 2:2 phase.

Finally, \(R^2 = 0.6129882\).
