However, the correlation effect over time in SUR model is not taken into account. In a standard linear model, we often assume the error terms are identically independent distributed.

研究表明，与没有考虑不同时间上的相关性的信度回归模型相比较，考虑了相关性的模型得到的估计值的误差较小。

Until now, all the results on central limit theorems under sublinear expectations require that the sequence of random variables is independent and identically distributed.

本文的目的是探究次线性期望理论中一个重要的结果：中心极限定理。
