Continuous and categorical mixed features
What function can i use to perform PCA on a dataset with mixed continuous and mixed features in rapidminer? I applied PCA on continuous features that have been standardized and left the categorical variables with dummy encoding only without PCA. Is there a dimensionality reduction method (e.g.FAMD) that can be used on such dataset? Thanks in advance.

Any other solution would not be a PCA.Best,Martin- Head of Data Science Services at RapidMiner -
