How to plot determinacy/indeterminacy regions?

But what is trend_inflation_iter in the last line ?

You don’t need that. It’s from an outer loop.

Dear Mr Pfeifer,
Thank you very much, I have found.

Dear Mr Pfeifer,
Sorry to disturb you again, but is it also possible to build a 3D determinacy plot in such code ? If yes, do you know how to do that ?
Thanks in advance.

How do you expect such a 3D-plot to look like, i.e. what should be shown on the axes?

I expect such graph to show me for 3 different parameters what is the determinacy region. I don’t know if it is possible but then I will have a 3D plot showing what are the intersection region of all 3 parameters that allow the model to be determinate and where the model is not. Do you think it is possible ?
Thanks again for your answers Professor.
Best,
Hugo

That’s not 3D, but 4D: 3 parameters plus 1 dimension for the outcome (determinate or not).

But when you have two parameters you only have a 2D plot no ?
Thanks

Here, the color encodes the third dimension. That does not work with three parameters as you would need to color a three-dimensional hypercube.

Ok perfect I understand.
Thank you very much Professor.
Best regards,
Hugo
