Re: Apply measures to Lookup
Hi Admin, thank you for your quick response. It was finally solved using your suggestion and changing de Data Table from "Lookup" to "Auxiliary with Lookup". Now I have another doubt. ¿Can I extract a value from the Data Table of a certain Year and save it as a constant? For exam...

Apply measures to Lookup
Good morning, I have some model predictions imported to Vensim as data as a Lookup structured like: [(1960,893.015)-(2070,32121.347)],(1961,32113.695),(1962,32105.358),(1963,32096.276)...The model is complex, so I cannot do it directly in VENSIM. My question is: how can I apply certain conditions to...

Thank you for your help.

Logistic Model from Data
Good morning, ¿does anyone know if I can carry out a Linear model or a logistic model directly from data? Now I am using variables of growth rate and carrying capacity calculated outside VENSIM (R, Python), but in the future I would like to directly calculate the growth rate inside VENSIM. Thank you...
