Correcting for On‐Site Sampling in Random Utility Models
提出一种计量方法，校正现场抽样导致的访问次数分布偏差，应用于太浩湖地区摩托艇休闲活动，发现未校正模型会高估或低估访问次数和福利。
Abstract This study demonstrates how the joint distribution of a set of conditional trip counts to a system of recreation‐sites can be adjusted for on‐site sampling. An econometric approach is proposed that addresses both the size‐biased distribution of the sampled visits and the weighted distribution of reported visits to ancillary destinations in a multivariate random utility framework. Estimation results indicate that uncorrected models produce biased estimates of trip counts and welfare measures. The empirical application examines jet skiing in the Lake Tahoe region.
