While not all useful estimators are unbiased, virtually all economists agree that consistency is a minimal requirement for an estimator.
虽然并不是所有的有用的估计量是无偏的，但是，一致性则是经济学家对估计量的最低要求。

Furthermore, we modify algorithm through compressing the parameter space so that the consistency and invariability of the estimator can be simultaneously guaranteed.
进一步，通过对参数空间进行压缩，使得改进后的收敛算法所得到的参数估计同时具有相合性及不变性。

Under certain conditions, We discuss the uniform strong consistency of kernal estimator for the density function.
