Which parameter is used to define the input table for the analysis? Is it possible to add a custom prefix to the names of the output reduced variables? How can I specify which variables are nominal for the training? What is the purpose of the mca action in SAS Viya? How can I save the dimensionality reduction model for future scoring?
