-creg is a fast tool for training linear and logistic regression models with
-l_1 and l_2 regularization. Its data (feature and response) format is
-compatible with ARKRegression.

-Logistic regression example (training only):
-  $ ./creg -x test_data/iris.trainfeat -y test_data/iris.trainresp --l1 1.0 > weights.txt
-
-Logistic regression example (training and testing):
-  $ ./creg -x test_data/iris.trainfeat -y test_data/iris.trainresp --l1 1.0 \
