The Correlation Analysis of Discrete Variables and Continuous Variables Based on Mutual Information

摘要：

　　As most Mutual Information method is limited to the correlation analysis between discrete variables in majority and tendency of choosing the characteristic variables with multi-values so far,in this paper we propose a new approach based on Mutual Information to measure the correlation of discrete variables and continuous variables.Then we take the fire control system of aircraft for example to calculate the correlation between fault types and monitor data indexes,and finally find the fault symptom classes.
