Sensitivity analysis on initial time

Post by Hossein »

Dear Tom/Administrator,

I want to do a sensitivity analysis on initial time! I am not sure such a work is possible or not because after running sensitivity, I got the results same as a simple run! In fact, I want to know if I defer the initial time one by one, what would be the results. Could you please help?

If you've run the sensitivity tests correctly, and the model is good, this would indicate that the model is not sensitive to changes in initial time. Do you expect the model to behave differently if you change it?

Dear Administrator,

Thanks for your reply. In fact, I expected that the results shifted to right side one by one year! because I used the Vector distribution by an increament of 1.

You need to look at the results and figure out why the shift hasn't happened.

Sensitivity data storage isn't set up to handle changes in the time axis, so this won't work.

You could use a command script instead.
