DOI: 10.1002/sim.9519
Abstract: We used Monte Carlo simulations to compare the performance of asymptotic variance estimators to that of the bootstrap when estimating standard errors of differences in means, risk differences, and relative risks using propensity score weighting.… read more here.

DOI: 10.1007/jhep03(2022)161
Abstract: Abstract Recently, boundary conformal field theories (BCFTs) have attracted much attention in the context of quantum gravity. This is because a BCFT can be dual to gravity coupled to a heat bath CFT, known as… read more here.
