Revised standards for statistical evidence.
Recent advances in Bayesian hypothesis testing have led to the development of uniformly most powerful Bayesian tests, which represent an objective, default class of Bayesian hypothesis tests that have the same rejection regions as classical significance tests. Based on the correspondence between these two classes of tests, it is possible to equate the size of classical hypothesis tests with evi...
متن کاملRevised evidence for statistical standards.
In (1), Johnson proposes replacing the usual p = 0.05 standard for significance with the more stringent p = 0.005. This might be good advice in practice but we remain troubled by Johnson’s logic because it seems to dodge the essential nature of any such rule, that it expresses a tradeoff between the risks of publishing misleading results and of important results being left unpublished. Ultimate...
متن کاملHigh Impact = High Statistical Standards? Not Necessarily So
What are the statistical practices of articles published in journals with a high impact factor? Are there differences compared with articles published in journals with a somewhat lower impact factor that have adopted editorial policies to reduce the impact of limitations of Null Hypothesis Significance Testing? To investigate these questions, the current study analyzed all articles related to p...
متن کاملMinimum statistical standards for submissions to Neuroimage: Clinical
The demand for reproducibility has reached fever pitch in scientific research (Baker, 2015), in particular in the field of psychology where many classic studies of human behaviour have not readily replicated (Klein et al., 2014). There aremanyexplanations for poor replication, including subject selection bias, poor experimental control, inconsistent measurement, demand characteristics, post-hoc...
متن کاملWeak statistical standards implicated in scientific irreproducibility : Nature News & Comment
Johnson compared the strength of two types of tests: frequentist tests, which measure how unlikely a finding is to occur by chance, and Bayesian tests, which measure the likelihood that a particular hypothesis is correct given data collected in the study. The strength of the results given by these two types of tests had not been compared before, because they ask slightly different types of ques...
