Webb27 feb. 2024 · Shapley值法是Shapley L.S于1953年提出,为解决多个局中人在合作过程中因利益分配而产生矛盾的问题,属于合作博弈领域。 应用 Shapley 值的一大优势是按照成员对联盟的边际贡献率将利益进行分配,即成员 i 所分得的利益等于该成员为他所参与联盟创造的边际利益的平均值。 本文从Shapley值法的概念定义以及实例计算两个方面展开叙述 … Webbshapley2,stat(r2_p) group(X1,X2 X3,X4 X5 X6) 几个需要注意的地方: 1.夏普利值分解没有考虑残差项,当R2或pseudo R2较小时,我们只能通过夏普利值分解说明在模型能解释 …

When you create a shapley object, if you do not specify a query point, then the software does not compute Shapley values. Use the object function fit to compute the Shapley values for the specified query point. Then create a bar graph of the Shapley values by using the object function plot.. Load the … port 443 blocked
Rolling problems: get decomposed R2, also called Shapley value
WebbAbstract. This program performs (exact additive) decomposition of a sample statistic by effects specified in factor list. To perform the Shapley decomposition, the effects are eliminated one by one, and marginal effects from each exclusion are weighted in such a way that all exclusion trajectories have equal weights. Webb5 jan. 2024 · 1- Run a regression and save the coefficients 2- Use the commands; shapley2 , stat (r2_w) matrix list e (shapley) 3- Run the same regression again and you will find that the coefficients will change ! I am not sure why this is the case, but I have tried with different regression and different data sets. Webb笔者按照这些资料,进行了stata实现: 第一,安装shapley命令,可使用“findit shapley”. 第二,安装完毕后,执行"help shapley"了解这一指令的基本操作. 在help文件中,已经给出了一个例子,如果要得到百分比的贡献,只需附加“percent”选项即可。. 结果如下 ... port 443 on the nat instance
