Concentration inequalities on the multislice and for sampling without replacement
Abstract
We present concentration inequalities on the multislice which are based on (modified) log-Sobolev inequalities. This includes bounds for convex functions and multilinear polynomials. As an application we show concentration results for the triangle count in the Erd\H{o}s--R\'{e}nyi model resembling known bounds in the case. Moreover, we give a proof of Talagrand's convex distance inequality for the multislice. Interpreting the multislice in a sampling without replacement context, we furthermore present concentration results for out of sampling without replacement. Based on a bounded difference inequality involving the finite-sampling correction factor , we present an easy proof of Serfling's inequality with a slightly worse factor in the exponent, as well as a sub-Gaussian right tail for the Kolmogorov distance between the empirical measure and the true distribution of the sample.
