Again, if I understand correctly, under no circumstances should the p-value
ever be outside of the range from 0 to 1. It's a probability, and no value
outside of that range makes any sense. But Incanter sometimes returns
p-values greater than 1.
I see that there was a recent fix made to
Simplicity was described as being a property of the artefact, not the
construct wasn't it? So I'm not sure what it means exactly for Clojure to
be simple or complex.
Does Clojure allow you to write artefacts that are simple? Yeah, I think
so, and I think it often makes it easier.
There was a
Also, the factory fns are available when you require/use the relevant
namespace, so the client doesn't have to use import as well.

What would be the best (idiomatic and efficiant) solution then?

Is there any way in Leiningen to add a dependency on the JDK's tools.jar?
Apparently it is possible with maven [1]

This lets you store a primitive constant value:
