[R] mixed exponential distribution

[Vishal Kiritkumar Mehta]

Hi all,

I have a 15min rainfall intensity dataset. I would like to fit a mixture
of two exponential distributions to this dataset, and then extract certain
quantiles from it.

Is there a package in R that will allow me to get maximum likelihood
estimates for the paramters, do goodness of fit tests, and then extract
quantiles from the fitted micture distribution? If not is there another
way to do this in R?

thanks,
vishal
