Hi!

I am trying to calculate statistics from an attribute into my list, but it is not possible with the StatisticsCalculator, I have to choose an element from the list when I select my attribute.

For the mean value it is easy to by pass this tool (ListSummer, ListElementCounter, ExpressionEvaluator et voilà!), but for the standard deviation, I don't see how to do it.

Can you open my eyes?

Thank you!

OK I think I've just figured it out.

I use the GOIDGenerator to create unique ID for each of me features.

After I use ListExploder to explode each of my features depends of the number of elements I have into my list. And After I use StatisticsCalculator (group by goid) and I choose my attribute.

I use Duplicateremover at the end to delete unwanted features.

So simple, it's a miracle I thought about that at the end of the day.
