Road traffic estimation and algorithmic routing in a spatially dependent network

Scandinavian Journal of Statistics, EarlyView.
ABSTRACT This work concerns a procedure to estimate the joint distribution of the per‐edge travel times in a road traffic network with spatial dependence. The constructed estimator, based on the realized travel times of a collection of independently operating probe vehicles traversing the network, is shown to be consistent and rate‐optimal.

When Do Authoritarian Regimes Use Digital Technologies for Covert Repression? A Qualitative Comparative Analysis of Politico‐Economic Conditions

Swiss Political Science Review, EarlyView.
Abstract Although autocracies increasingly learn how to integrate digital technologies into their covert repression toolbox, it remains unclear under which conditions they succeed in doing so. While some technologically developed autocracies seldom use covert repression, other technologically underdeveloped autocracies apply significantly more covert ...

A new upper bound for the growth factor in Gaussian elimination with complete pivoting

Bulletin of the London Mathematical Society, EarlyView.
Abstract The growth factor in Gaussian elimination measures how large the entries of an LU factorization can be relative to the entries of the original matrix. It is a key parameter in error estimates, and one of the most fundamental topics in numerical analysis. We produce an upper bound of n0.2079lnn+0.91$n^{0.2079 \ln n +0.91}$ for the growth factor
