comment How to define a bivariate skew normal distribution?
Univariate is generally easy because one can use the inverse cdf if all else fails. Multivariate will probably never be implemented in full generality. Also, pretty much everything exists in closed form for multivariate normals so special case code exists for those.

Sampling from user defined multivariate distributions isn't implemented. You will need to somehow use built in distributions or define your own method for sampling.

comment List all “duplicate” elements in Tally
@Mr.Wizard infix is a lovely obfuscator. If only there were short aliases for built in symbols for the purpose of code golf. Accessed via On["Golf"]. Though <<Golf' is probably better.

@Mr.Wizard I'm one as well but clearly my kung fu is not as strong as yours :)

Possibly GatherBy is what you need but without more specifics I can't say for sure.

comment Gauss Fit to List of 2D Points
@Rahul they make different assumptions about what the data represent. In your case we assume that the data points are left endpoints on the bins of a histogram (a perfectly reasonable assumption in this case). In the case of least squares there is a presumption that the data contain noise.

comment How should I iteratively refine a MixtureDistribution?
Part of the trouble I have is understanding what you mean by "configurations". If you could give an illustrative example of what you are attempting that would probably help. Data never hurts and short, clean, code always helps.

I think you will need to give some data driven example to give us a better idea how to help you.

comment Documentation for the Bounded option of SmoothKernelDistribution
It has been a long time since I saw the code but if memory serves it works by reflecting about the boundaries and truncating. The bandwidth is unaffected.

comment Fitting and plotting Weibull distribution
@SjoerdC.deVries I've unintentionally made things too complicated by trying to point out that the zeros get ignored. I was hoping to not get into any more detail than that :) Removing all reference to NonlinearModelFit
