The random variable 2−3X is of the form aX+b, with a=−3 and b=2. Thus, Var(2−3X)=(−3)2Var(X)=9⋅2=18. Is it always true that $E[X^2]≥(E[X])^2$? We know ...

Abstract: The commonly used global sensitivity analysis (GSA) can quantify the influence of random input variables on the variance of target outputs. To avoid the extremely large computational burden ...
