Does length of hospital stay reflect power-law behavior? A q-Weibull density approach

This paper studies whether or not the distribution of the length of hospital stay data follows power-law probability. For hospitals differing in size and specialization, our evidence shows that length of stay is well fitted by power-law density, independently of hospital size. Moreover, failure rate...

Description
Summary:This paper studies whether or not the distribution of the length of hospital stay data follows power-law probability. For hospitals differing in size and specialization, our evidence shows that length of stay is well fitted by power-law density, independently of hospital size. Moreover, failure rates differ across hospitals and are independent of hospital size and specialization.
