Routinely, so much well-intentioned effort is thwarted and morale is destroyed in organisations because of the lack of commitment to decisions. The likelihood and consequence of this is greatest where divergent groups, ie, different divisions, department or units are involved. This paper discusses a Group Model Building case study using qualitative system dynamics to create consensus, team lear...

In this paper, a new control chart to monitor multi-binomial processes is first proposed based on a transformation method. Then, the maximum likelihood estimators of change points designed for both step changes and linear-trend disturbances are derived. At the end, the performances of the proposed change-point estimators are evaluated and are compared using some Monte Carlo simulation experimen...

This article considers change-point testing and estimation for a sequence of high-dimensional data. In the case mean shift independent data, we propose new test which is based on U-statistic in Chen Qin (Ann. Statist. 38 (2010) 808–835) utilizes self-normalization principle (Shao J. R. Stat. Soc. Ser. B. Methodol. 72 343–366; Shao Zhang Amer. Assoc. 105 1228–1240). Our targets dense alternative...
