摘要:

In quality control the out‐of‐control detection problem is often one‐sided in the sense that quality decreases as one or more quality characteristics increase. Similarly in environmental monitoring the quality assessment is essentially one‐sided. Multivariate control charts like Hotelling's T2or Lowry's quadratic MEW MA are based on direction invariance. For the one‐sided multivariate problem I propose a new detector based on the restrictedMLEapplied to the MEW MA transform.
