Table 2. Averaged Cohen’s kappa values for all cluster solutions with 3–10 clusters.

	3 Clusters	4 Clusters	5 Clusters	6 Clusters	7 Clusters	8 Clusters	9 Clusters	10 Clusters
k-Means	0.65	0.74	0.90	0.64	0.62	0.62	0.60	0.63
LPA	0.80	0.38	0.38	0.29	0.30	0.32	0.30	0.19
Spectral	0.89	0.88	0.81	0.70	0.76	0.75	0.75	0.67
Mean	0.78	0.66	0.70	0.54	0.56	0.56	0.55	0.50

Each cell is an average value over 20 independent cluster computations on random data permutations; the mean value in the last row is the average over all cluster algorithms. LPA = latent profile analysis, k-Means = k-Means Clustering algorithm, Spectral = Spectral clustering algorithm.
