How to qualitatively describe distribution shapes

I have a distribution which looks a bit binomial, though with a cutoff, i.e.: $P(x) = 0$ if $x \le 0$, rises to a bell-shaped peak at around $x=0.2%$, appears to tail off exponentially until an ...

Are sample means for quantiles of sorted data unbiased estimators of the true means?

In studying income inequality, it is very common to look at sample means for deciles or quintiles of the sample, and to assume that the sample means are good estimators of the true means. In this ...
