Sum of rademacher random variables

WebLet X1, …, Xn be i.i.d. Rademacher random variables. That is, Pr(Xi = 1) = Pr(Xi = − 1) = 1 / 2. I was wondering if the following argument is true: Eexp(C ⋅ ( n ∑ i = 1Xi)4 /n3) = 1 + O(1 / n), where C ≥ 0 is a constant. I did some numerical simulations and the results validated this argument. I would appreciate it if anyone can give a proof. Web10 Apr 2024 · Background In many clinical trials the study interest lies in the comparison of a treatment to a control group regarding a time to event endpoint like time to myocardial infarction, time to relapse, or time to a specific cause of death. Thereby, an event can occur before the primary event of interest that alters the risk for or prohibits observing the latter, …
