A random shock is not random assignment [PDF]
Economics Letters, 2016 A random shock excludes reverse causality and reduces omitted variable bias. Yet a natural experiment does not identify random exposure to treatment, but the reaction to a random change from baseline to treatment. A lab experiment comparing higher certainty with higher severity of punishment for stealing (holding the expected value of the intervention ...

Random Trees in Random Graphs [PDF]
Proceedings of the American Mathematical Society, 1988 We show that a random labeled n n -vertex graph almost surely contains isomorphic copies of almost all labeled n n -vertex trees, in two senses. In the first sense, the probability of each edge occurring in the graph diminishes as n n increases, and the set of trees referred to as "almost all" depends

The Entry of Randomized Assignment into the Social Sciences
Journal of Causal Inference, 2019 Although the concept of randomized assignment in order to control for extraneous confounding factors reaches back hundreds of years, the first empirical use appears to have been in an 1835 trial of homeopathic medicine.

Random walks with random velocities [PDF]
Physical Review E, 2008 We consider a random walk model that takes into account the velocity distribution of random walkers. Random motion with alternating velocities is inherent to various physical and biological systems. Moreover, the velocity distribution is often the first characteristic that is experimentally accessible. Here, we derive transport equations describing the

Sampling-Based Robot Motion Planning: A Review
IEEE Access, 2014 Motion planning is a fundamental research area in robotics. Sampling-based methods offer an efficient solution for what is otherwise a rather challenging dilemma of path planning.

Random Walks in Random Environment [PDF]
Journal of Physics A: Mathematical and General, 2006 Random walks in random environments (RWRE's) have been a source of surprising phenomena and challenging problems since they began to be studied in the 70's. Hitting times and, more recently, certain regeneration structures, have played a major role in our understanding of RWRE's. We review these and provide some hints on current research directions and

Determining true difference between treatment groups [PDF]
Journal of Community Hospital Internal Medicine Perspectives, 2016 In this article, the author reviews the P value and how it is used to determine true difference of outcome in treatment groups. P value, standard deviation, standard error of the mean, bias, and confidence interval are discussed in common language, with ...

Frontiers in Psychiatry, 2021 Depression in adolescents and young adults is an increasing global health concern. Available treatments are not sufficiently effective and relapse rates remain high. The novel group-treatment program “Training for Awareness, Resilience and Action” (TARA)

Random walks and random permutations [PDF]
Journal of Physics A: Mathematical and General, 2001 A connection is made between the random turns model of vicious walkers and random permutations indexed by their increasing subsequences. Consequently the scaled distribution of the maximum displacements in a particular asymmeteric version of the model can be determined to be the same as the scaled distribution of the eigenvalues at the soft edge of the
