What do you call a distribution where most of the data points are at the minimum or maximum ...
Obtaining simple characterizations of the shape of a distribution was the purpose of Galtung's AJUS system proposed in Galtung (1969) and implemented, for instance, in the R agrmt package. As summariz …

Given two means and deviations, how can I compute the probability that x < y?
If your assumptions regarding the normality of $X$ and $Y$ are correct, then you have two normally distributed random variables $X\sim\mathcal{N}(\mu_X, \sigma_X^2)$ and $Y\sim\mathcal{N}(\mu_Y, \sigm …

How to calculate $P(A)$ given $P(A|B)$ and with B a continuous variable and $P(B)$ being a n...
Mathematically, it sounds like you have the following piecewise linear function for $P(A=1~|~B=t)$:
$$P(A=1~|~B = t) = \left\{\begin{array}{ll} 0 & \text{if}~t < T^- \\ \frac{t-T^-}{2(T-T^-)} & \tex …

Distributions over sorted lists
Let's assume $r_i$, the rank of list element $i$, has a value in $\{0, 1, \ldots, n-1\}$ for a list with $n$ elements (ties can be broken randomly). Then we could define the probability of selecting $ …

Can the difference of random variables be uniform distributed?
Consider the following example:
$$
X\sim\text{Unif}(0, 1) \\
Y = 1-X
$$
$X$ and $Y$ are identically distributed as the standard uniform distribution, and $X-Y = 2X-1$, so $X-Y\sim\text{Unif}(-1, 1)$ …

A good example of this is provided by Glen_b -Reinstate Monica at https://stats.stackexchange.com/a/189633/40036 . The question there was slightly different -- asking if normally distributed $X$ and $ …
