Minimizing NExpectation for a custom distribution in Mathematica
...tion compute the expected value.
For the expected value, we only need the PDF of your distribution. Let's extract it from your definition above into simple functions:
pdf[a_, b_, m_, s_, x_] := (1/(2*(a + b)))*a*b*
(E^(a*(m + (a*s^2)/2 - x))*Erfc[(m + a*s^2 - x)/(Sqrt[2]*s)] +
E^(b*(-m + ...
