本文介绍了在通用代数建模系统(GAMS)中实现CE-SAM估计技术的计算机代码。它定义了确定性环境中的估计问题;扩展了该方法以包括对控制总数中的误差的随机处理;总结了描述CE技术的方程,用于从有误差估计的不一致数据集开始估计一致的SAM;并提供了GAMS代码。
This paper documents the computer code implementing the CE-SAM estimation technique in GAMS (General Algebraic Modeling System). It defines the estimation problem in a deterministic setting; extends the approach to include a stochastic treatment of errors in control totals; summarizes the equations describing CE technique for estimating a consistent SAM starting from an inconsistent data set estimated with error; and provides the GAMS code.
