A Counter-Intuitive Correlation in a Random Tournament
Abstract. Consider a randomly oriented graph G = (V, E) and let a, s and b be three distinct vertices in V . We study the correlation between the events {a → s} and {s → b}. We show that, when G is the complete graph Kn, the correlation is negative for n = 3, zero for n = 4, and that, counter-intuitively, it is positive for n ≥ 5. We also show that the correlation is always negative when G is a...
متن کاملEfficient Simulation of a Random Knockout Tournament
We consider the problem of using simulation to efficiently estimate the win probabilities for participants in a general random knockout tournament. Both of our proposed estimators, one based on the notion of “observed survivals” and the other based on conditional expectation and post-stratification, are highly effective in terms of variance reduction when compared to the raw simulation estimato...

متن کاملAre !counter-intuitive" deontological judgments
A substantial body of evidence indicates that utilitarian judgments (favoring the greater good) made in response to difficult moral dilemmas are preferentially supported by controlled, reflective processes, whereas deontological judgments (favoring rights/duties) in such cases are preferentially supported by automatic, intuitive processes. A recent neuroimaging study by Kahane et al. challenges...
