摘要
采用对数正态分布作为精神病患者住院天数的概率分布模型。一般来说，不同的诊断和治疗机构的对数正态参数是不同的。来自几个患者样本的数据被提供为支持对数正态函数的证据。讨论了这一函数的含义，如涉及逗留时间的因素的乘法效应。
Abstract
The log-normal distribution is presented as a model for the probability distribution of length of hospitalization of mental patients. In general, the log-normal parameters differ for various diagnoses and treatment institutions. Data from several samples of patients are offered as evidence in support of the log-normal function. The implications of this function, such as the multiplicative effects of the factors involved in length of stay, are discussed.
