Abstract
Two statistical models are presented to describe the admission-discharge process of a psychiatric unit. Both models have the form of Markov processes. Common statistical terms such as length of stay in hospital, time off books, patients on books, and number of admissions are related to characteristics of the models. The models permit an assessment of the effect of studying statistical data based on cohorts of individuals rather than individuals considered separately. In addition, with refinement, it is expected that these models will permit the use of more sophisticated statistical methods in psychiatric research problems.
