The 10 indexes after the above data standardization are introduced into the SPSS software system to test the information correlation. From the test results in the following table, we can know that the absolute value of correlation Factor of safety or correlation influence coefficient is greater than 0.1 for most of the time variables in our country, which indicates the existence of extensive correlation among the variables. If there is some correlation between the control variables, then we can use principal component analysis to replace the original variables as completely as possible with as few principal components as possible, which can not only eliminate the correlation between the variables, and can be developed to achieve the effect of dimensionality reduction.
