The research question, scale of measurement and distribution of the outcome variable all have a bearing on the appropriate choice of statistical test. A statistical test can only be employed if the distribution assumptions of the test have been met. The interpretation of significance must be ...

Test (and its extension to diagnosis) should be considered as a challenging highly dimensional multivariate problem.Advanced statistical data processing offers a powerful set of tools, borrowed from the fields of data mining, machine learning or artificial intelligence, to get the most out of this ...

A test criterion based on the union-intersection principle of S. N. Roy is developed which, in the mUltlresponse case, is much more manageable computationally than the likelihood ratio criterion. For testing the hypothesis of one versus two different groups or clusters, however, the union-...

A method based on the t-distribution is used as a test of significance for finding and rejecting outlying observations in least squares adjustment. It is shown that the correlation between the residuals must be taken into account. When this is done some of the old statistical tests of significa...
