How to get values from Stats/List editor into home screen?

[tomhriojgerio]

If I need to use the value from a stats/list editor function like Poisson CDF in a function from the home screen, I am currently copying it down and typing it back in.

Is there some way to access the Poisson function from the home screen?


also is there some way to express the idea say X>5, it complains if I use Inf as the upper value.

Thanks
