| Abstract: | With the aim to the quantification of anomaly identification and extraction for observed or analyzed records, we present two statistical methods of earthquake corresponding relevancy spectrum(ECRS)and sliding mean relevancy (SMR).With ECRS method,we can obtain the abnormal confidence attribute of data in different value ranges.Based on the relevancy spectrum in different studied time-intervals,we convert the original time sequence into relevancy time sequence, and can obtain the SMR time series by using the... |
