我有这些命令来使用模型计算带宽规范  Y = G(XB) + epsilon

library(np)
bw <- npindexbw(formula=y~x1+x2)

summary(bw)

Single Index Model
Regression data (25 observations, 2 variable(s)):

      x1        x2
Beta:  1 0.1661524
Bandwidth:  1.031388
Optimisation Method:  Nelder-Mead
Regression Type: Local-Constant
Bandwidth Selection Method: Klein and Spady
Formula: y ~ 1 + x1 + x2
Bandwidth Type: Fixed
Objective Function Value: 0.4394019 (achieved on multistart 2)

Continuous Kernel Type: Second-Order Gaussian
No. Continuous Explanatory Vars.: 1

我想获得Coeffeicnts(Beta值)吗? 我的意思是在lm命令中我们可以将它作为列表处理(带有$符号)

答案 0 :(得分:0)

应该像

一样简单
coefficients(bw)
