how to cluster missing values in one cluster?
I would like to have 2 clusters from a data set. Basically one with examples that have missing values and the other with examples which dont have any missing values. As most Clustering algorithms do not allow missing values in data set, those missing values could be replaces by e.g. "0" . However still after that I m clueless on what exactly to do afterwards to have all missing values in one cluster.
Can anyone help?
