Monitoring Markov Dependent Binary Observations with a Log-Likelihood Ratio Based CUSUM Control Chart
… probability matrix is . We construct a CUSUM control chart for monitoring a proportion with correlated binary observations. First, we use the probability structure of a first-order Markov chain to derive a log-likelihood ratio based CUSUM control statistic. Then, we model this CUSUM …

Cumulative sum quality control charts design and applications
Classical Statistical Process Control Charts are essential in Statistical Control exercises and thus constantly obtained attention for quality improvements. However, the establishment of control charts requires large-sample data (say, no less than I 000 data points). On the other hand, we notice …

Prospective Spatio-Temporal Surveillance Methods for the Detection of Disease Clusters
… Knox surveillance method uses a cumulative sum (CUSUM) control chart for monitoring the local Knox statistic, which tests for space-time clustering each time there is an incoming observation. The detection of clusters of events occurring close together both temporally and spatially is important …

New progress in hot-spots detection, partial-differential-equation-based model identification and statistical computation
… Finally, we apply a Cumulative Sum (CUSUM) Control Chart to monitor the model residuals, which allows us to detect when and where the hot-spot event occurs. To demonstrate the usefulness of our proposed SSD-Tensor method, we compare it with several other methods in extensive numerical …
