An adaptive thresholding-based process variability monitoring
Abdella G.M.; Kim J.; Kim S.; Al-Khalifa K.N.; Jeong M.K.M.K.; Hamouda A.M.; Elsayed E.A.... more authors ... less authors ( Taylor and Francis Inc. , 2019 , Article)In high-dimensional processes, monitoring process variability is considerably difficult due to the large number of variables and the limited number of samples. Monitoring changes in the covariance matrix of a multivariate ... -
Control charts for variability monitoring in high-dimensional processes
Kim J.; Abdella G.M.; Kim S.; Al-Khalifa K.N.; Hamouda A.M. ( Elsevier Ltd , 2019 , Article)Monitoring process variability is associated with detecting changes in the covariance matrix of a multivariate normal process. Most monitoring methods estimate the sample covariance matrix and compare it with the in-control ... -
Monitoring and control of beta-distributed multistage production processes
Kim, S.; Kim, J.; Jeong, M. K.; Al-Khalifa, K. N.; Hamouda , A. M. S.; Elsayed, E. A.... more authors ... less authors ( Taylor and Francis Ltd. , 2019 , Article)Multistage statistical process control (SPC) is an effective procedure for ensuring quality of products in multistage manufacturing processes. Effective SPC approaches for monitoring and controlling quality in multistage ... -
Multivariate statistical process control charts based on the approximate sequential ?2 test
Kim, J.; Al-Khalifa, K.N.; Jeong, M.K.; Hamouda, A.M.S.; Elsayed, E.A. ( Taylor and Francis Ltd. , 2014 , Article)Similar to the univariate CUSUM chart, a multivariate CUSUM (MCUSUM) chart can be designed to detect a particular size of the mean shift optimally based on the scheme of a sequential likelihood ratio test for the noncentrality ... -
Penalized Conway-Maxwell-Poisson regression for modelling dispersed discrete data: The case study of motor vehicle crash frequency
Abdella G.M.; Kim J.; Al-Khalifa K.N.; Hamouda A.M. ( Elsevier B.V. , 2019 , Article)Statistical modelling of road crashes has been of extreme interest to researchers over the last decades. Such models are necessary for the investigation of the opportunities for road safety improvement. The motor vehicle ...
