Splet16.3 Disadvantages of a cluster design. The benefits of the clustered design are counteracted by some serious disadvantages. First of all, a clustered trial is far less efficient than a regular trial, because the unit of analysis is the cluster rather than the individual. Accordingly, much larger samples are needed to attain adequate power. SpletWith K-means clustering, you must specify the number of clusters that you want to create. First, load the data and call kmeans with the desired number of clusters set to 2, and using squared Euclidean distance. To get an idea of how well-separated the resulting clusters are, you can make a silhouette plot.
