摘要
本文直接将岭回归的原理和方法应用于动物性状的综合选择指数之中,提出了两种岭选择指数形式,并把它们同经典的无约束综合选择指数进行了比较,应用结果表明提出的岭选择指数实际可行。
In this paper,two forms of ridge selection index are presented by applying the theory and method of ridge regression directhy to animal multitrait, and a comparison is condueted between the classical selection index and the ridge selection index thru several comparable norms or criteria,Results indicate that the ridge selection index presented in the article is in practice workable.
