...特征，尌称为「不偏估值（unbiased estimate）；如果估值可能高估或低估术群体的术数，则称为「偏差估值（biased estimate）。 12 所谓区间推估，是指估量的结果提示一定范围的值（a range of value）， 这个范围尌称为估量区间（estimate interval）。
On the basis the parameters are separated for the biasedestimate 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.
