I have a failure time data that appears to be a mix of Normal and Exponential. >From engineering considerations, it is a competing failure modes problem. I would like to model it a mix of Normal and Exponential. The problem is similar to the 22 Mar 1999 post from Natasha Stout but I could find no replies to Natasha's post. The most intuitive Bugs code would be t ~ p*dnorm(mu,tau ) + (1-p)*dexp( lambda) Of course, that doesn't work. I would like to avoid the 'ones' trick if possible. Thanking all in advance...
