A function that takes two random variables and computes their expectation value and variance.

用广义最小二乘法辨识气动实验系统的参数，并采用最终误差预报估计模型阶次(Generalized Least Squares Identification of aerodynamic parameters of experimental system, using the final prediction error of the estimated model order)

最大似然估计法，TDOA测距时有锚节点，传感器节点的自定位(Maximum likelihood estimate for localization)

基于分数阶自抗扰控制的车辆1/4模型在混合路面启动工况仿真(Fractional-based vehicle ADRC 1/4 model start in the mixed road conditions simulation)

说明：  灰色模型预测是在数据不呈现一定规律下可以采取的一种建模和预测方法，其预测数据与原始数据存在一定的规律相似性(Grey model prediction is a kind of modeling and prediction method that can be adopted when the data does not show certain rules. There is certain regularity similarity between the prediction data and the original data)
