Thank you for your answers. I have other questions .... sorry
About Kalman Filtering, which is the differences with "normal" calibration? And with behavior reproduction test ?
Thank you
Giuseppe

Re: QGIS - Phyton - Vensim
I am at very early stage of my work. I am studying qgis because it is possible to use python to program qgis .
However I need to integrate gis and vensim because I need simulate time and geographical evolution of my model

Re: Calibration vensim model
Thank you for your answers. I did not know kalman filering it seems very interesting. I will try it.
So candidate parameters, could be parameters that are used to simulate growth ? In a disease model candidate parameter could be the infection rate, if I well understand.

Re: Calibration vensim model
Yes Tom, calbration is a very big problem. I have some questions.
The first question is how I can select the parameters to put into the vensim calibration form.
The second is how I select the model variables or costants that are calibrated with real data.
For now ... I have these questions.

Calibration vensim model
Hi everyone
I am looking documents or other materials about calibration of vensim model.
I read the manual of vensim. Are there other?
Thank you
Giuseppe

Re: QGIS - Phyton - Vensim
I am starting to combine qgis, vensim and python, so I appreciate very much if it is possible to work together to develop such model

Re: How can I use Vensim DLL in Python, Linux?
Hi
I develop model using vensim DSS in ubuntu 16.04 using WINE. I want use DDL to integrate my vensim models with other software and R or GIS.
Can I will do it using wine or is better to use virtual machine with windows ?
Thanks
Giuseppe

Re: grass software
for the first question, no i will try and tell you what happen
I try to use grass for linus not for win, but Grass gis could modify the wine. i do not know but i think that it is unlikely
thank you

Re: grass software
I simulate window by WINE.
vensim DSS does not start. Vensim PLE starts and works without any problems.
When I delete Grass Gis, and reinstall vensim DSS, vensim DSS works normally
unfortunately I have no error message.
Thank you

grass software
Dear
I have problem with vensim DSS version 6.3 (x32) and Grass software for gis. I use ubuntu 10.04.
the problem is that if I install grass gis, vensim DSS does not work, while vensim PLS version 6.3 (x32) works
Have you the same problem ?
thank you for your help
