R glmnet标准化的不同结果=错误

R glmnet标准化的不同结果=错误,r,glmnet,R,Glmnet,我正在运行glmnet,并尝试在使用standarized=FALSE预标准化变量时查看差异 library(glmnet) data(QuickStartExample) ### Standardized Way x_standardized <- scale(x, center = TRUE, scale = TRUE) y_standardized <- scale(y, center = TRUE, scale = TRUE) cv_standardized <- cv

我正在运行
glmnet
,并尝试在使用
standarized=FALSE
预标准化变量时查看差异

library(glmnet)
data(QuickStartExample)
### Standardized Way
x_standardized <- scale(x, center = TRUE, scale = TRUE)
y_standardized <- scale(y, center = TRUE, scale = TRUE)
cv_standardized <- cv.glmnet(x_standardized, y_standardized,
                             intercept = FALSE,
                             standardize = FALSE, standardize.response = FALSE)
destandardized_coef <- coef(cv_standardized)[-1] * sd(y) / apply(x, 2, sd)
destandardized_coef
mean(y) - sum(destandardized_coef * colMeans(x))

### Let glmnet Stanardize
cv_normal <- cv.glmnet(x, y)
coef(cv_normal, cv_normal$lambda.min) %>% as.numeric()
我的问题是,如何提取相同的结果,以及为什么目前的系数以这种方式不同

提前谢谢
