Recursive partitioning methods have become popular and widely used tools for nonparametric regression and classification in many scientific fields. Especially random forests, which can deal with large numbers of predictor variables even in the presence of complex interactions, have been applied successfully in genetics, clinical medicine, and bioinformatics(More)
Menstrual cycle phase-dependent changes in appetite in women with premenstrual syndrome has not thus far been systematically demonstrated. In this study of 21 patients with premenstrual syndrome and 13 control subjects, there were significant increases in appetite in both groups, with a greater effect of menstrual cycle phase on appetite in the patients.(More)
To test the hypothesis that causalgia is a reflex sympathetic dystrophy with focal sympathetic hyperactivity in the painful area, we studied skin conductance, temperature, and a radiometric index of blood flow in 10 patients and 10 controls. Skin conductance was significantly higher, and both skin temperature and blood flow index were significantly lower in(More)
Despite the growing popularity of the zebrafish model system, the optimal husbandry conditions for this animal are not well defined. The aim of this study was to examine the effect of stocking density on reproductive performance in zebrafish. In this study, undertaken by eight different zebrafish facilities, clutches of at least 200 wild-type zebrafish(More)
A number of interventions to improve gait in individuals with cerebral palsy (CP) have been reported in the literature. The aim of this study was to perform a meta-analysis of these studies to determine the overall efficacy of these interventions. Effect sizes (Hedge's g) for spatiotemporal measures of gait (velocity, cadence, stride length) pre- and(More)
Because of the unique combination of physical (e.g. bloating, water retention) and psychological (e.g. mood, memory) symptoms associated with premenstrual syndrome (PMS), various hypothalamic and pituitary hormones have been implicated in the pathophysiology of PMS. We measured plasma adrenocorticotropic hormone (ACTH), arginine vasopressin (AVP) and atrial(More)
Any family of learning machines can be combined into a single learning machine using various methods with myriad degrees of usefulness. For making predictions on an outcome, it is provably at least as good as the best machine in the family, given sufficient data. And if one machine in the family minimizes the probability of misclassification, in the limit(More)
Many games and sports, particularly races, involve outcomes in which competitors are rank ordered rather than simply a single winner being declared. An abundance of approaches exists to estimate competitor ability from rank orderings, often with the purpose of making accurate forecasts for future competitions. We propose a Bayesian state-space framework for(More)
