The dataset from Steiner et al. (1999) on A synthetic dataset from the Danish meat inspection -- useful for illustrating the beta-binomial CUSUM.

## Details

Steiner et al. (1999) use data from de Leval et al. (1994) to illustrate monitoring of failure rates of a surgical procedure for a bivariate outcome.

Over a period of six years an arterial switch operation was performed on 104 newborn babies. Since the death rate from this surgery was relatively low the idea of surgical "near miss" was introduced. It is defined as the need to reinstitute cardiopulmonary bypass after a trial period of weaning. The object of class sts contains the recordings of near misses and deaths from the surgery for the 104 newborn babies of the study.

The data could also be handled by a multinomial CUSUM model.
