摘 要 主要考慮了生長曲線模型中的參數(shù)矩陣的估計. 首先基于Potthoff-Roy變換后的生長曲線模型, 采用不同的懲罰函數(shù):Hard Thresholding函數(shù), LASSO, ENET, 改進LASSO, SACD給出了參數(shù)矩陣的懲罰最小二乘估計.接著對不做變換的生長曲線模型, 直接定義其懲罰最小二乘估計, 基于Nelder-Mead法給出了估計的數(shù)值解算法. 最后對提出的參數(shù)估計方法進行了數(shù)據(jù)模擬. 結果表明自適應LASSO在估計方面效果比較好.

關鍵詞 懲罰最小二乘估計;Hard Thresholding函數(shù);SCAD 懲罰函數(shù);改進LASSO
