%description
The gamma-Orthogonal Matching Pursuit (gamma-OMP) is a recently suggested
modification of the OMP feature selection algorithm for a wide range of
response variables. The package offers many alternative regression models,
such linear, robust, survival, multivariate etc., including k-fold
cross-validation. References: Tsagris M., Papadovasilakis Z., Lakiotaki K.
