− The Accredited Laboratories at their Certificate have described its best measurement capabilities (BMCs) for the more or less routine calibrations. This BMCs were usually evaluated by interlaboratory comparisons (ILCs), the proficiency testing (PT) schemes as described by the ISO Guide 43. The NMIs traditionally organize the ILCs for the NABs providing the travelling standards, the reference(...

Often research in judgment and decision making requires comparison of multiple competing models. Researchers invoke global measures such as the rate of correct predictions or the sum of squared (or absolute) deviations of the various models as part of this evaluation process. Reliance on such measures hides the (often very high) level of agreement between the predictions of the various models a...

A parallel implementation of an efficient method for comparison of multiple DNA sequences is presented. The method is described in terms of a conceptual tree data structure for the sequences to be compared. The parallel algorithm shows efficient utilization of processors on an Encore Multimax computer in a sample comparison of 11 sequences totaling over 4000 bases. Timing data show the strong i...

In experiments involving many variables, investigators typically use multiple comparisons procedures to determine differences that are unlikely to be the result of chance. However, investigators rarely consider how the magnitude of the greatest observed effect sizes may have been subject to bias resulting from multiple testing. These questions of bias become important to the extent investigator...
