WebIf your data contains both numeric and categorical variables, the best way to carry out clustering on the dataset is to create principal components of the dataset and use the principal component scores as input into the clustering. Remember that u can always get principal components for categorical variables using a multiple correspondence ... WebClustering for Mixed Data K-mean clustering works only for numeric (continuous) variables. For mixed data (both numeric and categorical variables), we can use k-prototypes which is basically combining k-means and k-modes clustering algorithms. For numeric variables, it runs euclidean distance.
