attrCUSUM

attrCUSUM is tools for statistical design of attribute VSI CUSUM chart. It currently provides informations on monitoring of mean increase including

• Average number of sample to signal (ANSS).
• Computation of suitable control limits for

fixed sampling interval (FSI) scheme.

• Computation of the longer sampling interval for

variable sampling interval (VSI) scheme.

• Average time to signal (ATS).
• A matrix of transition probabilities for Markov chain approach.

These tools might be extended to more complicated CUSUM control chart and we leave these issues as our future works.
