hello
I wanted to ask about the solution of parametric models.
Is it possible to solve parametric model (like Austria PVC model solved using Gabi, Excel, and Umberto given in Practical handbook for MFA) using STAN?
Hoping for a quick response.
Thank you

Hi Nikita,
I´m not quite sure, what you mean.
You can define linear relationships of flows. that might be the closed to what I understand when i hear parametric model?
But you may elaborate your question, a bit. What specifically do you want to do.
Best regards from Berlin.

Yes.
I wanted to solve linear equations or equations with dependent parameters.
For example "Austria PVC Model", this example is provided for a solution using Gabi. I wanted to solve using Stan
Sample equation:
Export Rate = X value
Sales = Y value
Export = Export Rate*Sales
Thank you for your response.
Best Regards,
Nikita

Hi Nikita,
if you go to Edit > Edit relation... you can define linear relationships of the processes.
I just tried that for the year 1960, as you can see in the screenshot below.
I just defined 2 relationships and set the values for recycling and sales in 1960.
However, as Stan is not able to work with non-linear fuctions you need to calculate the sales rate (hird-order polyno-mial function) outside STAN (in Exccel for instance and copy the values into STAN [FAQ as a section on how to import values from excel)

Thank you very much for your response.
I will try to do it this way.
