WebDetails: The sequence of models implied by lambda is fit by coordinate descent. For family="gaussian" this is the lasso sequence if alpha=1, else it is the elasticnet sequence.. From version 4.0 onwards, glmnet supports both the original built-in families, as well as any family object as used by stats:glm().The built in families are specifed via a character string.

Weblasso 模型与ridge 模型. 针对多维度特征的回归模型,可以考虑选用lasso 或者ridge,因为特征之间很有可能具有多重共线性(彼此包含或关联),而step.lm,lasso等算法能自动处理这个问题,针对高度相似的特征,lasso会随机选其中一个。. Lasso和Ridge的公式非常相似 ...
