针对因变量和自变量均存在随机误差的模型，提出了一种参数估计方法--两阶段变量误差模型。尽管曾经提供了一个例子来演示如何以逐步的方式使用该模型，但如果没有可以在PC或UNIX平台上运行的计算机程序的支持，该模型似乎不会广泛适用。在这项研究中，在MATLAB语言编写的程序代码的两阶段误差变量模型，四个估计问题的解决方案。人们希望，代码将使该方法易于使用的系统生态学研究或任何研究，涉及估计问题，其中一些变量受到错误，而其他人没有随机误差。(C)2002爱思唯尔科技有限公司。保留所有权利。
A parameter estimation method called the two-stage error-in-variable model was introduced to the models that have both dependent and independent variables subject to random errors. Even though an example was once provided to demonstrate how to use the model in a step-by-step fashion, it appears the model would not be widely applicable without the support of computer programs that can be run on either a Pc or UNIX platform. In this study, the programming codes written in the MATLAB language are presented for the two-stage error-in-variable model; four estimation problems are solved with the program. It is hoped that the codes would make the method easy to use in systems ecology studies or any research involving estimation problems in which some variables are subject to errors while others have no random errors.
