A transition rate model for first admissions to psychiatric institutions

This paper describes the application of a parametric transition rate model, the generalized log-logistic model, to the duration of first admissions to psychiatric institutions. The final model included diagnosis, gender, age, living conditions and year of admission as covariates. Characteristics of the log-logistic model are described extensively. Parametric transition models offer challenging and promising possibilities to model duration of hospital stay. Copyright (C) 1999 John Wiley & Sons, Ltd.
