Previous results have indicated that the OLS estimator of the vector of regression coefficients can be nearly as efficient as the best linear unbiased estimator when the regression errors follow a spatial process with root in the vicinity of unity. Such results were derived under the assumption of...

FRM I Quantitative efficiency的意思是需要unbiased estimator的方差最小吗?如何证明是最小的? 添加评论 0 0 1 个答案 DD仔_品职助教 · 2022年02月16日 嗨,从没放弃的小努力你好: 同学你好, 是这个意思,具体请看讲义截图128页如下图: 找到方差最小的方法是最小二乘法OLS,同学可以再去听一下section...
In the presence of multicollinearity, the ordinary least squares (OLS) estimator could become unstable due to their large variance, which leads to poor prediction. One of the popular solutions to this problem is Ridge Regression. Logistic Regression makes no assumption about the distribution of the...

Furthermore, it is essential to determine the suitability of using a stochastic frontier function and the statistical significance of inefficiency among the sampled countries before applying an SFA estimator. To evaluate this, we use the Coelli (1995) skewness test on the residuals obtained from the...
These authors express the weakness in terms of the size of the bias of the IV (i.e., 2SLS) estimator relative to that of the OLS estimator. 17 The negative coefficient of the EEGIi in the reduced-form of the model is reflecting the fact that, in our sample, energy governance is ...
The Johansen co-integration test was not used in the present investigation because it assumes that the variables under examination must be integrated into the first difference when assessing the presence of a unit root. However, the GMM estimator also includes several assumptions that solely deal ...
