We present a new procedure for combining P-values from a set of L hypothesis tests. Our procedure is to take the product of only those P-values less than some specified cut-off value and to evaluate the probability of such a product, or a smaller value, under the overall hypothesis that all L hypotheses are true. We give an explicit formulation for this P-value, and find by simulation that it c...

The success of most software companies depends largely on software product quality. High product quality is usually a result of advanced software development processes. Hence, improvement actions should be selected based on sound knowledge about the dependencies between software product quality attributes and software development processes. This article describes a method for developing product...

The spectral transformation Lanczos method is very popular for solving large scale Her-mitian generalized eigenvalue problems. The method uses a special inner product so that the symmetric Lanczos method can be used. Sometimes, a semi-inner product must be used. This may lead to instabilities and breakdown. In this paper, we suggest a cure for breakdown by use of an implicit restart in the Lanc...

to survive in today’s competitive environment, companies need continues improvement to achieve goals such as increasing the accuracy of targeting, improving product or service. however, there is no improvement guaranty without performance evaluation. an organization must assess current performance before embarking on any improvement. if it does not, it will have no baseline from which to determ...
