Prospective Spatio-Temporal Surveillance Methods for the Detection of Disease Clusters
… determining the in-control average run length (ARL) performance for different space and time closeness thresholds as well as for different control limit values. The effect of nonuniform population density and region shape on the in-control ARL is explained and some issues that should be …

Dynamic Probability Control Limits for Risk-Adjusted Bernoulli Cumulative Sum Charts
… tool for monitoring clinical and surgical performance. In practice, however, use of a fixed control limit for the chart leads to quite variable in-control average run length (ARL) performance for patient populations with different risk score distributions. To overcome this problem, the …

Process Monitoring with Multivariate Data:Varying Sample Sizes and Linear Profiles
… is taken at this sampling point. The performance of the sequential sampling (SS) MEWMA control chart is compared to the performance of standard control charts. It is shown that that the SS MEWMA chart is substantially more efficient in detecting changes in the process mean vector than …
