| Abstract: | A test procedure using chi-square statistics is proposed for determining a threshold in an ordered sequence of correlated proportions. The procedure is based on the multivariate Bernoulli model. It is applied to the problem of ascertaining when visual acuity has stabilized in a group of patients with regular follow-up after a vision-reducing acute abnormality. |
