Hypothesis: In the field of research, a hypothesis refers to a proposed explanation to a question, and it is often referred to as an ''educated guess''. The hypothesis serves as a starting point for further research. For example, a researcher may hypothesis that girls are smarter than boys...
The null hypothesis significance test (NHST) is the most frequently used statistical method, although its inferential validity has been widely criticized since its introduction. In 1988, the International Committee of Medical Journal Editors (ICMJE) warned against sole reliance on NHST to substantiate ...
Difference Between the Null Hypothesis and Alternative Hypothesis The null hypothesisrepresents the absence of an effect or difference, while the alternative hypothesisproposes a specific effect or change. In other words,the alternative hypothesis represents the opposite of the null hypothesis. The main d...
Using the regression model which does not detrend time series properly results in rejecting the null hypothesis in large samples even when the null is true. Extensive simulation illustrates the finite same performance of the tests introduced in this paper. The multivariate tests using Andrews' ...
A perennial objection against Bayes factor point-null hypothesis tests is that the point-null hypothesis is known to be false from the outset. We examine the consequences of approximating the sharp point-null hypothesis by a hazy ‘peri-null’ hypothesis instantiated as a narrow prior distribution...

Minimum Bayes factors are commonly used to transform two-sided p-values to lower bounds on the posterior probability of the null hypothesis, in particular the bound −e·p·log(p). This bound is easy to compute and explain; however, it does not behave
In this post, learn what it means when you fail to reject the null hypothesis and why that’s the correct wording. While accepting the null hypothesis sounds more straightforward, it is not statistically correct! Before proceeding, let’s recap some necessary information. In all statistical hypot...
