摘要
The lower bound principle (introduced in Bohning and Lindsay (1988, Ann. Inst. Statist. Math., 40, 641-663), Bohning (1989, Biometrika, 76, 375-383) consists of replacing the second derivative matrix by a global lower bound in the Loewner ordering. This bound is used in the Newton-Raphson iteration instead of the Hessian matrix leading to a monotonically converging sequence of iterates. Here, we apply this principle to the multinomial logistic regression model, where it becomes specifically attractive.
