[R] mixture distribution with positive and negative probabilities
Hi! Any ideas on which package (e.g. mixdist, flexmix, etc) how I could fit a mixture of say 3 Gaussian functions where 2 have their proportions, means, and sigmas, and the third has a mean, sigma but a negative proportion. Basically I'm trying to fit a mixture model to a distribution that I know is the sum of 3 distributions, where one inhibits the other two. Is there such a thing? Thanks in advance!
