Removing the underlying implementations and making a GammaDistributionImpl implement the ChiSquareDistibution interface is risky and difficult venture, there would be no way to enforce the "immutability" of the scale parameter required to maintain its "ChiSquareness".

Good point. I am +0 for dropping ChiSquaredDistributionImpl, but -1 for exponential (because of efficiency). Unless others object, I will make that change. Thanks for pointing this out.
I do not mind HOW it is in the package, but I would argue against an option where the user has to know which parameters need to be fed to an more general underlying distribution, especially when it is a common used one such as chi-square. Unless of course, you want to limit this package to a hard core public only.
