consistent estimate
相合估计
相合性又称一致性,是研究统计量统计大样本性质的一种。相合性表明:只要取样本量足够大,就可以使得估计误差在一定意义下任意地小。相合性在统计中是研究得最深入的大样本性质,这是因为其重要性所决定的,即,如果一个估计量没有相合性,则无论你取多大的样本,用这一估计量对被估参数进行估计仍然有较大可能产生较大误差。因此,在适当的样本量之下,这种估计很难有良好表现;另外,在所有统计大样本性质中,相合性的要求最低,容易得出相对深入的结果。相合性所研究的内容:判定从某种途径得到的估计量是否为相合,在何种条件下为相合,或在给定条件模型下,是否存在以及何种条件下存在相合性的问题。
