However, popular strategies (e.g., wavelet shrinkage is proposed for effectively handle in these issues) tend to select models with more predictors than necessary. This paper proposes a simple estimate for tuning parameters based on wavelet shrinkage of penalized method (Ridge and Elastic-Net) compared with the classic penalized method depending on the tail probability behavior of the response variables and using simulation experiments for (10%) data with contamination and real data. The comparing results between the proposed method with a classic penalized method based on the statistical criterion (MAE and MSE). It was concluded that the wavelet shrinkage of penalized method gives the best results and a more accurate classical method for all simulations and real data based on (MAE and MSE) criteria.</p>}, number={3}, journal={PalArch’s Journal of Archaeology of Egypt / Egyptology}, author={Asst.Prof. Dr. Nabeel George Sulaiman and Alan Ghafur Rahim}, year={2022}, month={Jul.}, pages={424-439} }
