L1 Regularization Parameter
Use this option to specify the value (between 0 and 1) used to multiply the L1 penalty term in LASSO or ElasticNet.
L1 corresponds to a multiplier on a regularization term that represents a norm on the regression coefficients and is the sum of absolute values. L1 is specified only when you want to directly specify this multiplier.
Note : This option is available only when L1 is specified as the Criterion for Stopping Model Selection .
When a value of 0 is specified, this parameter is estimated via some other means. Refer to the SAS PROC GLMSELECT documentation has more details.
To Specify the L1 Regularization Parameter:
*
Select either LASSO or ElasticNet as the Model Selection Method .
