execute `run!()` or `paramscan()` multiple times using the same parameters

[yunhwankim2]

In many cases, experiments using ABM are executed multiple times using the same parameters and results of their averages and/or confidence intervals are usually reported. Thus, I would like to request a functionality in run!() and paramscan() functions to execute multiple times using the same parameters and record all the data. Many thanks in advance.

This is a very useful feature! (not sure if it already possible in some way though)

Yes, it is possible, using paramscan, and making the varied parameter the RNG seed. It is also mentioned in the docstring of paramscan:

simply don't change any other parameter besides the seed.

To report confidence intervals this is a standard processing of the resulting data frame and the quantile function.

Thank you for the reply. I tried to find the docstring, and it was found in the ensemblerun! (https://juliadynamics.github.io/Agents.jl/stable/api/#Agents.ensemblerun!) rather than paramscan. Is it ensemblerun! that you intended to refer to?

[Datseris]

It doesn't matter. Either can work for you. Either can run many simulations changing parameters. Just make the seed the changing parameter.

Okay. I see. Thank you so much.
