estimability of coefficient [统计] 系数的可估性
estimability of parameters 参数的可估性
estimability of parameter [统计] 参数的可估性
The definition of parameter estimability is proposed for parameter estimation problem with finite measurement information based on the definition of system estimability.
基于系统可估计性定义，本文根据有限测量信息的参数估计问题特点，提出了系统的参数可估计性定义；
The relationship between parameter estimability and the number of data sets is discussed. The effectiveness of the proposed analysis can be demonstrated by the results of linear and nonlinear systems.
最后分析了当测量变量有多组测量时对系统参数可估计性的影响，通过线性与非线性实例验证了分析结果的有效性。
