K-means silhouette scores (top row), proportion of correctly identified clustering (second row), proportion of correctly identified number of clusters (third row), and the proportion of observations correctly assigned to their subgroup, each computed through 100 iterations of simulation. Datasets of varying sample size (x-axis) and two features were sampled from populations with equidistant subgroups that each had the same 3-factor covariance structure. The simulated populations were made up of two unequally sized (10 and 90%) subgroups (left column); or two, three, or four equally sized subgroups (second, third, and fourth column, respectively)
