Previous research has introduced the conditional phase-type distribution as a model that can suitably represent a skewed survival distribution conditioned on a network of inter-related variables. The technique has successfully been applied to modeling the stay of elderly patients in hospital which typically includes extreme stays in hospital resulting in a highly skewed survival distribution. This...
This paper extends a method for modeling the survival of patients in hospitals to allow the expected cost to be estimated for the patients' accumulated duration of time in care. An extension of Bayesian network (BN) theory has previously been developed to model patients' survival time in hospitals with respect to the graphical and probabilistic representation of the interrelationships between the...
