Functions for fitting linear and generalized linear models with variable selection. The functions can automatically do Stepwise Regression, Lasso or Elastic Net as variable selection methods. Lasso and Elastic net are improved and handle factors better (they can either include or exclude all factor levels).

Performs Regularization on Structural Equation Models
Uses both ridge and lasso penalties (and extensions) to penalize
specific parameters in structural equation models. The package offers additional cost functions, cross validation, and other extensions beyond traditional SEM.
