On the basis the parameters are separated for the biased estimate by means of partial prior knowledge, and unbiased estimates of all parameters to be evaluated are obtained.
在此基础上，用部分验前知识，进一步对该有偏估计作了参数分离，从而得到全部待估参数的无偏估计。
Finally, we obtained three robust biased model fitting methods which were called as robust principal component estimate, robust ridge estimate and robust root-root estimate respectively.
三种方法分别是稳健主成分估计、稳健岭估计和稳健根方估计。
