Exponential inequalities for self-normalized martingales with applications
arXiv:0707.3715 · doi:10.1214/07-AAP506
Abstract
We propose several exponential inequalities for self-normalized martingales similar to those established by De la Peña. The keystone is the introduction of a new notion of random variable heavy on left or right. Applications associated with linear regressions, autoregressive and branching processes are also provided.
