A New Estimator Based on Likelihood Function for Drift Time of Change in Poisson Rate Parameter [PDF]

International Journal of Research in Industrial Engineering, 2014
Although a control chart can signal an out-of-control state in a process, but it does not always indicate when the process change has begun. Identifying the real time of the change in the process, called the change point, is very important for ...
