In lessSEM: Non-Smooth Regularization for Structural Equation Models

.smoothElasticNetValue

Description

smoothed version of non-differentiable elastic LASSO penalty

Usage

.smoothElasticNetValue(parameters, tuningParameters, penaltyFunctionArguments)

Arguments

parameters	vector with labeled parameter values
tuningParameters	list with fields lambda (tuning parameter value), alpha (0<alpha<1. Controls the weight of ridge and lasso terms. alpha = 1 is lasso, alpha = 0 ridge)
penaltyFunctionArguments	list with fields regularizedParameterLabels (labels of regularized parameters), and eps (controls the smooth approximation of non-differential penalty functions (e.g., lasso, adaptive lasso, or elastic net). Smaller values result in closer approximation, but may also cause larger issues in optimization.)

Value

penalty function value
