WebRademacher Random Variables Rademacher random variables can be defined in terms of Bernoulli random variables. If Y is a Bernoulli random variable, then X = 2Y −1 is a Rademacher random variable [3]. Conversely, if X is a Rademacher random variable, then (X + 1) /2 is a Bernoulli random variable. Web13 Apr 2024 · The proof of the theorem in the present paper closely follows the scheme in , the novelty at each step being of one of the following two types: either all the argument is obtained from the one in automatically via the replacement of \(\sum_{j=1}^\infty\) by \(\sum_{j=1}^{k}\) everywhere, or we still need to make additional estimates related to …
