Hi,
Let Z be a r.v. from N(0, σ^2) and let Y = Z^2*exp(Z)/(1 + exp(Z))^2.
What is the exptected value of Y, E(Y)?
The delta method (Taylor expansion) doesn't work since
the errors seem to accumulate.
Any suggestions? This is a non-standard problem related to my research and I am totally stuck with this one...
