Again, there is no such thing as a “Cumulative Probability Distribution”. It’s right up there with Pink Unicorns.

What you showed was something that starts at zero and increases monotonically to 1. THAT is a Cumulative Distribution Function (as I remember those are the only two requirements for both continuous and discrete CDFs). Just wiki the darn thing and learn.

Here, I’ll even do it for you:

In the circles I frequent, that's what we call it.

But, since you asked to be off this ping list, I guess it doesn't really matter what I call it.

A rose by any other name would still smell as sweet.
