comment Empirical Cumulative Distribution Function
I accepted kirma's answer because it came first and gives an exact solution. I however upvoted your answer because it is a useful approximation (and works directly with Mathematica 8). Thanks!

comment Empirical Cumulative Distribution Function
@kirma Thanks. Very useful (works alright with Mathematica 8 as you suggest). Yes, I am dealing with empirical data, so I don't know exactly the data generating process and would hence prefer not to impose any parametric assumptions (and some of my other plots seem to fit less neatly normal distributions).

comment wrong use of _?NumberQ?
Thanks. I had tried what you suggest and it didn't work --in fact, when I copy/pasted your code and ran it, it didn't work at first... It turns out (I just realize) that the introduction of ?NumberQ in the definition of the function has to be done on a clean function (it doesn't replace an existing definition). In the end, the solution is indeed to use f[a_, b_, x_?NumericQ] BUT clearing f[] beforehand (don't know if this is obvious but it cost me a lot of time).

comment wrong use of _?NumberQ?
Thanks, yes; the problem is that the constraint is nonalgebraic. I edited the question above and included a complete example at the end.
