It is shown that in most typical situations in psychological research (when either observing no, small, medium or large effects) default Bayes factors are asymmetric in information, i.e., they result in unequal
The hypothesis testing is carried out to ensure whether the sample results are statistically significant at a given confidence level.Answer and Explanation: A type I error in hypothesis testing is the one where the null hypothesis is rejected even though it is true....
This decision process is prone to the following kind of error:we may fail to reject the null hypothesis when it is false. Errors of this kind are dubbed Type II errors, in order to distinguish them from Type I errors, which occur when the null hypothesis is rejected despite being true. ...

Consider the problem of testing the linear hypothesis on regression coefficients in the nested error regression model. The standard F-test statistic based on the ordinary least squares (OLS) estimator has the serious shortcoming that its type I error rates (sizes) are much larger than nominal ...

Depending on the selected mode, the alpha error or the acceptance or rejection range can be calculated. ...

The null hypothesis is that there is no difference between two (or more) groups apart from random variation, and is central to statistical hypothesis testing. If the differences between the groups are more than can be accounted for by random variation, then the judgment may be made that the ...

Key words: MAP; hypothesis testing; probability of error Introduction Lower bounds on the probability of error are of great importance in system design and performance analysis in many applications, such as signal detection, communications, and ...
