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.

住院时间长短是否反映了幂律行为？q-威布尔密度法

本文研究住院天数的长度分布是否遵循幂律概率。对于规模和专业不同的医院，我们的证据表明，住院时间与幂律密度完全吻合，而与医院规模无关。此外，各医院的故障率各不相同，并且与医院的规模和专业程度无关。
