Central limit theorem: negative moments

Let $X_{1},\ldots,X_{N}$ be i.i.d. random variables with mean 0 and variance 1. Assume that $X_{i}$ are continuous random variables with all finite moments and a nice density function. Let \begin{equation} S_{N} =…

Problem on convergence in distribution of a random vector

The issue is that I have to prove the following with limited resources. Problem: Let $X_n$ and $Y_n$ be p-dimensional random vectors. Show that if $X_n − Y_n \xrightarrow{P} 0$ and $X_n \xrightarrow{D} X$ , where $X$ is a p-dimensional random…
