WebTo estimate the number of clusters (NOC), you can specify NOC= ABC in the PROC KCLUS statement. This option uses the aligned box criterion (ABC) method to estimate an interim number of clusters and then runs the k-means clustering method to produce the final clusters.The NOC= option works only for interval variables. If the NOC= option is …

WebDescription. K-means is one method of cluster analysis that groups observations by minimizing Euclidean distances between them. Euclidean distances are analagous to measuring the hypotenuse of a triangle, where the differences between two observations on two variables (x and y) are plugged into the Pythagorean equation to solve for the …
