%description
Efficient procedures for fitting the regularization path for linear,
binomial, multinomial, Ising and Potts models with lasso, group lasso or
column lasso(only for multinomial) penalty. The package uses Linearized
Bregman Algorithm to solve the regularization path through iterations.
Bregman Inverse Scale Space Differential Inclusion solver is also provided
for linear model with lasso penalty.
