You could try estimating the conditional cumulative distribution function
with quantile regression by estimating a large interval of quantiles (e.g.,
0.01 to 0.99 if your n is large enough). Quantile regression will readily
handle skewed and heterogeneous responses. Some finessing required to

Just a little note about computational methods for Tweedies and compound Poisson-gammas. The package statMod has a Tweedie family that can be used in
glm(), the package Tweedie has functions for density calculations (and other things), the package fishMod (my own package) has methods to
