与传统的捕获和再捕获方法相比，Laska, Meisner, and Siegel（1988）的单样本方法（LMS）能够在单次调查的基础上估计种群的大小N *。例如，可能希望在一周样本的基础上估计去年精神健康中心服务的不重复的个人数量。确定每个抽样个体最后一次从事定义人口的活动的时间。用一种简单的方法推导了N *的LMS估计量及其无偏性，并在有附加信息的情况下引入了改进的LMS估计量。利用已知真实人口规模的精神卫生服务数据，对这一程序进行了实证评估。与标准LMS估计器相比，扩展LMS估计器的性能有了实质性的改进。
In contrast to classical capture recapture methods, the single-sample method of Laska, Meisner, and Siegel (1988) (LMS) enables estimation of the size of a population, N∗, on the basis of a single survey. For example, it may be desired to estimate the unduplicated number of individuals served by a mental health center during the last year on the basis of a 1-week sample. The time since each of the sampled individuals last engaged in the activity that defines the population is ascertained. The LMS estimator of N∗and its unbiasedness property are motivated in a simple way, and an improved LMS estimator is introduced if additional information is available. An empirical assessment of the procedure is made using mental health service data for which the true population size is known. The performance of the extended LMS estimator is a substantial improvement over the standard LMS estimator.
