例句与用法
- If the assumption fails , we say the model exhibits heteroskedasticity
如果这个假定不成立,我们说模型存在异方差性。 - " for methods of analyzing economic time series with time - varying volatility arch
所发明的“自动递减条件下的异方差性” - The model which has such kind of property is referred to as heteroscedastic regression model
扰动项具有异方差性的模型称为异方差模型。 - One of the important hypotheses of classical linear regression model is that the random disturbances have equal variance
经典线性回归模型的一个重要假设就是回归方程的随机扰动项u _ i ,具有相同的方差,也称同方差性。 - However in most economic phenomena , this kind of hypothesis is not necessary true . sometimes the disturbances vary with the observations . this is called heteroscedasticity
但在大多数经济现象中,这种假设不一定成立,有时扰动项u _ i的方差随观察值的不同而变化,这就是异方差性。 - If it is estimated by the method of ols , it will bring about serious effect : the variances of the parameter estimators are not the least , and the accuracy of estimation and prediction decreases
如果对异方差模型进行ols估计,就会产生严重的后果:参数估计量的方差不具有最小方差性;估计与预测的精度降低。 - The article analyses whether the theory of emh market can explain some phenomena on capital market . we provide some evidence for the non - normal , non - gaussian distribution , auto - correlation , non - linear and heteroskedasticity character of stock price
