Regression Discontinuity Marginal Threshold Treatment Effects
In regression discontinuity models, where the probability of treatment jumps discretely when a running variable crosses a threshold, an average treatment effect can be nonparametrically identi ed. We show that the derivative of this treatment effect with respect to the threshold is also nonparametrically identi ed and easily estimated, in both sharp and fuzzy designs. This marginal threshold tr...
متن کاملError threshold in simple landscapes
We consider the quasispecies description of a population evolving in both the “master sequence” landscape (where a single sequence is evolutionarily preferred over all others) and the REM landscape (where the fitness of different sequences is an indipendent, identically distributed, random variable). We show that, in both cases, the error threshold is analogous to a first order thermodynamical ...
متن کاملOn the treatment of threshold effects in SUSY spectrum computations
We take a critical view of the treatment of threshold effects in SUSY spectrum computations from high-scale input. We discuss the two principal methods of (a) renormalization at a common SUSY scale versus (b) integrating out sparticles at their own mass scales. We point out problems in the implementations in public spectrum codes, together with suggestions for improvements. In concrete examples...
متن کاملEffects of threshold resummation
We investigate effects of threshold resummation of logarithmic corrections lnN in Mellin space quantitatively. Threshold resummation leads to enhancement of next-to-leading-order QCD predictions for jet production at large jet transverse energy, which is in the trend indicated by experimental data. We show that this enhancement is completely determined by the behavior of threshold resummation a...
