DEA ---关于SBM模型的选择

请问SBM-GRS模型是什么意思？一般规模报酬模型，怎么解释？

我做的时候就是随便选择了一个。。。。不过有一点不明白。。就是整个模型是怎么表现出非期望产出在模型里的重要性的呢。。

楼主没有论坛币，能不能支付宝转账你发我邮箱？

您好，SBM 模型弄明白没有啊？我现在也头大呢 ，能不能给指导一下啊？我邮箱1310976851@qq.com

I和O一看就知道是基于投入到下和产出导向  C和V 一看就知道是CRS和VRS啊

您好，请问您会DEA模型中的SBM 模型吗 ？软件里面有 SBM super-SBM ,其中还分好多个分支，请问您对这个模型了解吗 ？如若了解可不可以给详细讲解一下呢？我邮箱1310976851@qq.com

一般规模报酬

DEA-Solver applies the following notation to describe DEA models.  

Model Name - I or O – C, V or GRS

where I or O corresponds to “Input”- or “Output”-orientation, and C or V to “Constant” or “Variable” returns to scale, respectively. For example, “AR-I-C” means the Input-oriented Assurance Region model under Constant returns-to-scale assumption. In some cases, “I or O” and/or “C or V” are omitted. For example, “CCR-I” indicates the Input oriented CCR model that is naturally under constant returns-to-scale. “GRS” indicates the “General” returns to scale model. Models with the GRS extension demand to input two parameters through keyboard. The one is the lower bound L of the sum of lambdas (λ) (see Page 138 of the Springer Introductory Text) and the other its upper bound U.  “Bilateral” “Congestion” and “FDH” have no extensions. The abbreviated model names correspond to the following models. (Chapter number indicates that of the Springer Introductory Text.)

SBM_I_C 和 SBM_I_V应该是规模不变CRS和规模可变VRS的区别吧

您好，您写的这段英文出自哪篇文章，能分享一下吗？谢谢
