A surveillance system for metabolic disorders in Japan.
Statistical procedures based on a Poisson hypothesis for surveying serial occurrences of incidence were developed. Three methods, the z-test, the cusum technique and the sequential test were applied in a study of a nationwide screening system on newborns for hereditary metabolic disorders in Japan. It was found that the statistical tests well detected human errors involved in data processing.
