Geometric approximation for the number of returns of a transient Markov chain to its origin

Fraser Daly, Seva Shneer

Given a discrete-time, transient Markov chain, we establish explicit total variation error bounds in the approximation of the number of visits to its starting state within the firs…

Approximations for the number of maxima and near-maxima in independent data

Fraser Daly

In the setting where we have independent observations of a random variable , we derive explicit error bounds in total variation distance when approximating the number of obs…

Biasing with an independent increment: Gaussian approximations and proximity of Poisson mixtures

Fraser Daly

By exploiting the well-known observation that size-biasing or zero-biasing an infinitely divisible random variable may be achieved by adding an independent increment, combined with…

Rates of convergence for extremal spacings in Kakutani's random interval-splitting process

Fraser Daly, Andrew Wade

Kakutani's random interval-splitting process iteratively divides, via a uniformly random splitting point, the largest sub-interval in a partition of the unit interval. The length o…

Stein's method for asymmetric Laplace approximation

Fraser Daly, Robert E. Gaunt, Heather L. Sutcliffe

Motivated by its appearance as a limiting distribution for random and non-random sums of independent random variables, in this paper we develop Stein's method for approximation by…

First passage percolation on Erdős-Rényi graphs with general weights

Fraser Daly, Matthias Schulte, Seva Shneer

We consider first passage percolation on the Erdős--Rényi graph with vertices in which each pair of distinct vertices is connected independently by an edge with probability $…
