The aveEffPlot function in the DAMisc package uses the average marginal effects approach to make the same graph. aveEffPlot(bin.mod1, "rgdpna_pc", conflictData, nvals=50) If you don’t like the lattice plot, you can specify plot=FALSE and the data will be returned. outDat <- av...
模型中一般有两类参数:一类需要从数据中学习和估计得到,称为模型参数(Parameter)——即模型本身的参数,一般称为 \theta 。比如,线性回归直线的加权系数(斜率)及其偏差项(截距)都是模型参数。还有一类则是机器学习算法中的调优参数(tuning parameters),需要人为设定,一般称为超参数(Hyperparameter)。比如,正则化系数λ...

Finally, the 3D graph is displayed using the persp (perspective graph) function: XML > persp(x,y,z, col=color[facetcol], phi=20, theta=-35, + ticktype="detailed", d=5, r=1, shade=0.1, expand=0.7) The persp function has a lot of optional, named parameters....
