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

[R] Defining an ex-gaussian PDF

2005-08-27 Thread Michael Kubovy
