Correlation between polynominal attributes?
Hi, I work with the employee attrition data set and have a question. The data set contains numerical values, bionominal and polynomial values. With the nummerical and bionominal values, I can use the operator correlationmatrix and see how the dependency on the target variable attribution is. How do I do that with polynomial values like business travel? Could I use the operater nominal to nummerical? or are there better alternatives to show the dependencies between the label and the polynomial values?
