[R] Help needed with ks.test

[Emanuele Mazzola]

Hello to everybody,

I'd like to submit a problem I'm dealing with, and I can't get an answer to 
by myself.
I have to test if my data come from a specific probability distribution, of 
which I know the analytic form both of the p.d.f. and the c.d.f.
Namely, it is the hypoexponential distribution, sum of two exponentials with 
different parameters.
Is there any way I can manage the task with ks.test?
It's not straightforward to compute the inverse of the c.d.f in order to 
simulate data from that distribution...

Thank you very much in advance for your kind answers!
See you
EM
