计算一对向量场的李导数。

一种迭代保留信息变量以在多元校准中选择最优变量子集的策略。 可以选择最优变量子集的方法。 在本研究中，一种考虑可能的策略提出了变量之间通过随机组合产生的交互作用，称为迭代保留信息变量 (IRIV)。 此外，变量被分为四类强烈信息量、弱信息量、非信息量和干扰变量。 在此基础上，IRIV 既保留了每个迭代轮中的强信息变量和弱信息变量，直到没有无信息和干扰变量存在。 三个数据集被用来研究 IRIV 的性能以及偏最小二乘法 (PLS)。

Iterative Solution of Nonlinear Equations in Several Variables (book)

Iterative Solution of Nonlinear Equations in Several Variables provides a survey of the theoretical results on systems of nonlinear equations in finite dimension and the major iterative methods for their computational solution. Originally published in 1970, it offers a research-level presentation of the principal results known at that time. Although the field has developed since the book originally appeared, it remains a major background reference for the literature before 1970. In particular, Part II contains the only relatively complete introduction to the existence theory for finite-dimensional nonlinear equations from the viewpoint of computational mathematics. Over the years semilocal convergence results have been obtained for various methods, especially with an emphasis on error bounds for the iterates. The results and proof techniques introduced here still represent a solid basis for this topic.
