Both applications use a novel simulation-based multiple testing correction procedure that is very flexible and less conservative than the traditional false discovery rate approach.Goovaerts, PierreGoovaerts P (2007) Spatial uncertainty in medical geography: a geostatistical perspective.

Hypothesis TestingExpected Net BenefitsThis work investigates whether to conduct a medical study from the point of view of the expected net benefit taking into account statistical power, time and cost. The hypothesis of this paper is that the expected net benefit is equal to zero. Methods: ...
testing procedures and associated sample size calculations for case–control and tnd studies. these tests, all based on a simple logistic regression model, are a standard wald test, a continuity-corrected wald test, and a score test. the wald test performs poorly in both case–control and tnd...
Null Hypothesis Significance Testing (NHST) has been well criticised over the years yet remains a pillar of statistical inference. Although NHST is well described in terms of statistical models, most textbooks for non-statisticians present the null and alternative hypotheses (H0 and HA, respectively)...
3. Bayesian hypothesis testing: An alternative to NHST "(…) prior and posterior are relative terms, referring to the data. Today's posterior is tomorrow's prior." Lindley [52, p. 301]. In the field of statistics, probabilities can be interpreted under two predominant paradigms: Frequentist...
Before testing for phenomena, you form a hypothesis of what might be happening. Your hypothesis or guess about what's occurring might be that certain groups are different from each other, or that intelligence is not correlated with skin color, or that some treatment has an effect on an outcom...
2.2.3 Typical Independent Variables in HCI Research Independent variables are closely related to the specific research field. It is obvious that the factors frequently investigated in medical science are drastically different from those examined in physics or astronomy. In the HCI field, independent var...
Neuropsychological testing verified that the deficiencies were not in the domain of general or specific intelligence, memory, sensation, perception, or in other known standard tests of cognitive abilities.

(the latter being the operative hypothesis generating activity). For the former, the results are handled in a manner quite similar to the hypothesis-testing study. In the latter case, the participant may be asked if they would be willing to return for further phenotyping to help us determine...
This chapter describes the concepts of null hypothesis, research hypothesis, and examples of hypotheses. Testing the population mean against a known reference value, testing whether or not a new observation comes from the same population and using confidence intervals is explained. 展开 DOI: 10.1016...
