Method and device for determining index correlation

Abstract

The present invention proposes a method and device for determining the correlation of indicators. The method includes: obtaining the index values ​​of the sampling points of the first index and the second index in the same time period; according to the index values ​​of the adjacent sampling points of the first index, obtaining The first change amount of the first index in the time interval corresponding to the adjacent sampling points, and use the first change amount of all sampling points to obtain the first change amount set of the first index in the time period; according to the second index adjacent The index value of the sampling point, determine the second change amount of the second index in the time interval corresponding to the adjacent sampling point, and use the second change amount of all sampling points to obtain the second change amount set of the second index in the time period ;According to the first change amount set and the second change amount set, obtain the confidence degree of the correlation between the first index and the second index; if the confidence degree is greater than or equal to the preset first threshold, then determine the first index and the second index There is a relationship between them. The method has high degree of automation and high efficiency.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a method and device for determining the relevance of indicators. Background technique [0002] When monitoring the running status of a device, it is usually necessary to establish an association relationship of the monitoring indicators based on the collected monitoring indicator data. At present, the correlation between monitoring indicators is mainly established manually based on experience. However, this method has a low degree of automation, takes a long time, and has poor usability when there are many monitoring devices. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the first purpose of the present invention is to propose a method for determining the correlation of indicators, through the index values ​​of the sampling points of the first...

Problems solved by technology

[0004] For this reason, the first purpose of the present invention is to propose a method for determining the correlation of indicators, through the index values ​​of the sampling points of the first indicator and the second indicator in the same time period, calculate the correlation between the two indicators in all sampling intervals Change amount, and obtain the change amount set, obtain the confidence degree of the two indicators according to the change amount set of the two indicators, and then determine whether there is a relationship between the two indicators according to the confidence degree, and realize the specific data calculation. The correlation between the two indicators can be determined, which solves the problems of time-consuming, low efficiency, and poor usability in the existing technology of manually establishing the correlation relationship of indicators based on experience
