Save request to copy the cluster membership variable as well as the distance of each 2014-10-24 K-means clustering requires all variables to be continuous. Other methods that do not require all variables to be continuous, including some heirarchical clustering methods, have different assumptions and are discussed in the resources list below. K-means clustering also requires a priori specification of the number of clusters, k. Dealing with missing data in cluster analysis is almost a nightmare in SPSS. Returning to our case study, where we have no complete cases, if we run it using the default options in SPSS's K-means cluster we get the following error: Not enough cases to perform the cluster analysis.
