本文描述了对mvis的重大更新，使其更接近S. van Buuren和C. g.m. Oudshoorn在R和S-PLUS中实现的MICE系统的功能集（详细信息，请参阅http://www.multiple-imputation.com）。为了与mvis明确区分，Stata新版本的主要程序被称为ice。我将详细介绍如何使用这些新特性，并使用真实数据给出一个实际的说明性示例。mvis的所有设施都被冰保留。本文还描述了对多输入数据集计算估计的组合算法的一些改进。
This article describes a substantial update to mvis, which brings it more closely in line with the feature set of S. van Buuren and C. G. M. Oudshoorn's implementation of the MICE system in R and S-PLUS (for details, see http://www.multiple-imputation.com). To make a clear distinction from mvis, the principal program of the new Stata release is called ice. I will give details of how to use the new features and a practical illustrative example using real data. All the facilities of mvis are retained by ice. Some improvements to micombine for computing estimates from multiply imputed datasets are also described.
