  1. I just got 10 hits from 'RSiteSearch("convolution of exponential and normal")', at least two of which look like they might interest you.
  2. I similarly got 27 hits from 'RSiteSearch("convolution distribution")', several of which mention the "distr" package, which you might find useful.
  3. I doubt if this solves your problem, but I hope you find it useful. If you have other questions for this list, I encourage you to PLEASE do read the posting guide! "http://www.R-project.org/posting-guide.html". It can increase the chances that you will get a useful reply quickly.
