Loss functions for specific probability distributions?
There is indeed a paper titled Loss Distributions that provides the limited expected value functions $L(x)$ for several probability distributions (on page 15). It is directly related to the first-...

How can I model regression with an asymmetric loss function?
I suspect you want to minimize $\sum\limits_i \left[k_1\max(e_i,0)^2 + k_2\max(-e_i,0)^2\right]$. For instance, $a=0.5$ would correspond to $k_1 = 0.25$ and $k_2 = 2.25$).
This can be formulated as a ...

clarification on the definition of loss function
We want to measure the quality of a solution, that is given two solutions, $x, y \in A$, I want to tell if $x$ is a better solution than $y$.
Real numbered as an ordered field enable us to compare two ...
