A really useful feature for this template would be for it to automatically scrub a `NetworkAggregations` group of any aggregations that aren't referenced in other model configs. Oftentimes during model...

Also probably worth implementing for skim-based aggregations. Right now the way they're doing it at LCOG for example is using `misc.compute_range()` from urbansim.utils: https://github.com/urbansim/lcog/blob/master/lcog/variables.py#L468-L497.

@cvanoli @janowicz this should be good to go now folks.

@janowicz the second FutureWarning that @cvanoli mentions isn't a big deal and should resolve itself in the future. The first FutureWarning, however, is happening during IPU when household weights that...

Ah, yes, that does make sense to think of it from the perspective of data filters. Approach 2 might be better for the time being then.

I figured out how to perform stratified sampling while generating the entire universe of alternatives for all observations at once, and included the fix in the latest commit here. Just...

@smmaurer so that def prob is the most common use case for folks, however, I'm not sure we necessarily want to give them that ability until we also implement functionality...

Responding to your points, @maurer: 1. I thought that McFadden's positive conditioning theory showed explicitly that random sampling of alts from the full universe shows produces _unbiased_ estimates, no? 2....

So, as long as this ticket is still open, I can probably get the proportional strata implemented, to accommodate strata that are not evenly distributed but still sampled randomly and...

Not sure if this fix elicits its own version increase, perhaps could just get included in the next release if there's one in the works?
