Minimizing NExpectation for a custom distribution in Mathematica

阅读更多关于 Minimizing NExpectation for a custom distribution in Mathematica

问题 This relates to an earlier question from back in June: Calculating expectation for a custom distribution in Mathematica I have a custom mixed distribution defined using a second custom distribution following along the lines discussed by @Sasha in a number of answers over the past year. Code defining the distributions follows: nDist /: CharacteristicFunction[nDist[a_, b_, m_, s_], t_] := (a b E^(I m t - (s^2 t^2)/2))/((I a + t) (-I b + t)); nDist /: PDF[nDist[a_, b_, m_, s_], x_] := (1/(2*(a +

If you have been using Mathematica for a while you probably have grown attached to the documentation center. There is always something new that you find in those pages. Let it be options for a function or just some examples that at some point did not seem useful to you. It is likely that you have written packages with your specialized functions that you use all the time. Sometimes you might think of a neat example to use with your function but it is likely that it ends up being forgotten somewhere in your hard disk. If you had written it to the documentation at the moment you thought of it
