术语“协方差函数”的详细信息

英译术语:

covariance function

汉语语境:

在对现有的基于等价权的稳健估计的弊端进行分析的基础上。建立起一套基于调整观测量方差-协方差阵的稳健最小二乘估计理论。包括相关ρ函数、相关φ函数、等价方差-协方差函数、等价方差-协方差因子、影响函数、崩溃污染率等。

英语语境:

Depend on analyzing the abuse of equivalent weights, a set of self contained theory system on robust estimation based on equivalent variance covariance are established, which include function, equivalent variance covariance function、influence function and breakdown point.

英译术语:

autocovariance function

汉语语境:

在对一类简单的能够产生混沌现象的映射过程进行统计特性分析的基础上，利用其协方差函数特点，介绍了一种自协方差函数为c（k）＝c（0）αk，0＜α＜1形式的混沌信号的简单设计方法及应用，从而为有目的地产生混沌信号，利用及分析混沌信号提供了新的信号获取途径。

英语语境:

By analysing the statistical properties of a class of chaotic maps, a new method is provided by this paper to design chaotic signals whose autocovariance function has the form of c(k)=c(0)α k, 0<α<1. It can also provide a new method for us to generate, utilize and analyse chaotic signals in application.
