SPSS: K-means analysis. What criteria can I use to state my choice of the number of final clusters I choose. Using a hierarchical cluster analysis, I started with 2 clusters in my K-mean analysis. However, after running many other k-means with different number of clusters, I …

The first k cases with no missing values are initially selected as cluster centers. Then the remaining cases are examined, in the order they are in the file. 3.

K-Means Cluster Analysis This procedure attempts to identify relatively homogeneous groups of cases based on selected characteristics, using an algorithm that can handle large numbers of cases. However, the algorithm requires you to specify the number of clusters. You can specify initial cluster centers if you know this information. Cluster analysis with SPSS: K-Means Cluster Analysis Cluster analysis is a type of data classification carried out by separating the data into groups. The aim of cluster analysis is to categorize n objects in (k>k 1) groups, called clusters, by using p (p>0) variables.
