R package Feature Correlation Matrix
Status: First version (0.4.0) ready to get pushed to CRAN, minor changes under development already !
Authors: Dr. Guido Möser/ Ilja Muhl (in alphabetical order)
Notes: If you want to run the featureMatrix()-function, the two other functions, cv.test() and icc(), have to be available!
What it does: Estimates the correlation between categorical and numerical features (and the target variable)
Parameter: - both variables numerical: Product-Moment-Correlation by Bravais-Pearson - both variables categorical: Cramer’s V (based on the Chi²-Test of Independence) - one variable categorical and the other numerical: ICC (Intra-Class-Correlation) based on classical ANOVA by Fisher
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
