Re: recursive formula.

[trammell]

What is P()? One? Or is there some special recipe telling what to do when P() has one argument?

A complete example calculation would help immensely.

[BioGeek]

the r-values are scores, and P is a probability:
so P(r₁) is the chance of having score r₁,
P(r₁,r₂) is the chance of both having score r₁ and score r₂,
and so on.

[rsteinke]

Ah, so P() is 1 (the probablity of having anything happen).

Ok, you'd have to ammend my code with

    return 1 if !@_:

at the top or something

[trammell]

So is it the case that:

  P(r1) = (r1 - r0) P()
        = r1

Correct?

[BioGeek]

Yes, that's correct

Or, like rsteinke explained it much better than I can in the chatterbox:
"If P(r_1) is the probability of getting r_1, and P(r_1,r_2) is the probability of getting r_1 and r_2, then P() is the probability of anything at all happening (unconstrained), which is 1"
