摘要
对于误差相关的线性模型,本文就有约束与无约束的情形分别给出了回归系数的 G M 估计弱相合的充分必要条件,并举例说明误差相关的线性模型中回归系数的 L S的估计的弱相合性与均方相合性并不等价。
In this paper,sufficient and mecessary conditions of weak consistency of the Gauss Markov estimates of reression coefficient,either satisfying linear restrictions or not ,in a linear regression model with correlated errors are given respctively.An example is also presented to show that weak consistency is not epuivalent to meansquare consistency of the LS estimates of regression coefficient in a regression model with correlated errors.
