This paper investigates the level and development of cross-country stock market dependence using daily returns on stock … modelling the dependence between markets using parametric families of copulas which offer various alternatives to the commonly … assumed normal dependence structure. Moreover, the dependence across stock markets is allowed to vary over time through a …

We provide a familiy of tests for the IID hypothesis based on generalized runs, powerful against unspecified alternatives, providing a useful complement to test designed for specific alternatives, such as serial correlation, GARCH, or structural breaks. Our tests have appealing computational...

Products that do not meet the specification criteria of an intended buyer represent a challenge to the producer in maximizing profits. To understand the value of the optimal process target (OPT) set at a profit-maximizing level, a model was developed by Shao et al. (1999) involving multiple...

Abstract: In diagnostic medicine, there is great interest in developing strategies for combining biomarkers in order to optimize classification accuracy. A popular model that has been used when one biomarker is available is the binormal model. Extension of the model to accommodate multiple...

In diagnostic medicine, there is great interest in developing strategies for combining biomarkers in order to optimize classification accuracy. A popular model that has been used for receiver operating characteristic (ROC) curve modelling when one biomarker is available is the binormal model....
