Monitoring of Social Network and Change Detection by Applying Statistical Process: ERGM [PDF]
Journal of Optimization in Industrial Engineering, 2020 The statistical modeling of social network data needs much effort because of the complex dependence structure of the tie variables. In order to formulate such dependences, the statistical exponential families of distributions can provide a flexible ...

Statistical Process Control Using Control Charts with Variable Parameters
, 2023 An extremely important issue in quality management is monitoring and diagnosing processes, and, subsequently, supervising them using so-called control charts. In typical production processes, charts with constant parameters are commonly used, such as x-R,
