Mark each cluster with a unique number. Sample size requirements and analysis. We can easily number each borough from 1 to 32.
X1p 2x21 x22 x23.
A good rule of thumb for sample size in LCA is a sample size of at least 250 unique people places or things. Some publications using cluster analysis mention O2 m where m is the number of attributes and O is the number of objects or observations as a rule of thumb for the size of the dataset. For a pre-specified available number of clusters k investigators need instead. Researchers usually use pre-existing units such as schools.
