]]>What are the equivalent allocation functions of Vensim software in Stella ? Dose Stella supports allocations functions ?

]]>Does Stella professional supports cycle time? ]]>

I am using Stella 10.0.6. I can find the time-stamped option for a flow. why is that ?

]]>Thank you very much for the reply. The problem was fixed! and all the measurements were included. I ran GEOtop model coupled with PEST for calibration purposes successfully.

Now, the only issue is “Weights”, which as you know should be given to each observation group properly within the PEST control file! For TEST_RUN, to calculate the residuals I ran the PEST, which the “weights” was set as “1” to all the groups.

Now to run a FORMAL PEST, I need to assign the Weights to each group as best as possible to make sure that the contributions to the total objective function from all different observation groups are approximately equal!!

I have read the PEST-Manual several times, but still it’s confusing to me! how to assign the best Weights properly based on the residuals!?

Can I send the PEST_Outputs to you to have a look at and guide me how to do this? at: support@iseesystems.com

I am looking forward to hearing from you,

Best
