马利科夫准则有效的判据

Validity Condition of Malikov Criterion

针对马利科夫准则易产生误判而失效的缺点,分析了马利科夫准则失效的情况和原因,根据t检验法提出了马利科夫准则有效的判据。该判据根据测量数据列前、后半部分数据均值的一致性,判断马利科夫准则是否有效,从而准确判断测量数据是否含有线性系统误差。

As Malikov criterion may produce wrong estimates in applications, we study the condition under which the Malikov criterion becomes invalid, and give the reasons. The condition for the Malikov criterion being valid is brought forward using a t-test method. The condition can be used to verify validity of the Malikov criterion according to consistency of the mean of measured anterior and posterior half data. Thus a conclusion can be drawn on whether linear system errors exist in the measure data list.
