Statistical distributions in the thermal model
… is made to use the thermal model to determine statistical particle number fluctuations in the presence of exact conservation laws. A basis is provided, which will be useful to extend the range of applications of the thermal model with both a large number of conserved charges as well as quantum …

The role of statistical distributions in vulnerability to poverty analysis
… is compounded by the need to select appropriate statistical distribution for weather anomaly measures and household characteristics. We address these challenges by analyzing household consumption data from the Living Standards Measurement Study survey in Niger and systematically evaluating how …

A risk and reliability management appraisal of company failure. An application of risk and reliability managment methodology to the analysis and identification of pattern, causes and symptoms of company failure, including formation of a Data Bank for failed companies.
… the identification of the failure pattern. Best distributions describing failure behaviour of companies were also determined and the validity and application of various statistical distributions were examined. A detailed examination of the histories of some large companies which failed during the …
