Ward's method
In statistics, Ward's method is a criterion applied in hierarchical cluster analysis. Ward's minimum variance method is a special case of the objective function approach originally presented by Joe H. Ward, Jr. Ward suggested a general agglomerative hierarchical clustering procedure, where the criterion for choosing the pair of clusters to merge at each step is based on the optimal value of an objective function. This objective function could be "any function that reflects the investigator's purpose." Many of the standard clustering procedures are contained in this very general class. To illustrate the procedure, Ward used the example where the objective function is the error sum of squares, and this example is known as Ward's method or more precisely Ward's minimum variance method.

"Identifying subgroups of potential youth smokers using latent profile " by David Lee Villegas
The purpose of this thesis was to compare Ward's method cluster and latent profile analysis in their identification of subgroups of youth that are not yet smokers but may be in the near future. The variables used to identify these subgroups are measures indicative of behavior change known as the Pros of Smoking, Cons of Smoking, and Situational Temptations to Smoke. Both analyses were conducted within 5 random subsamples generated out of a larger pool (N=3493) of 6th grade children attending elementary school in the state of Rhode Island. Evidence for the existence of a 4-cluster solution of potential youth smokers was found with both methods despite variability in actual case assignment of subjects to subgroups within and across methods. The use of Ward's method and latent profile analysis together allowed for the identification of additional cases at elevated risk for smoking acquisition.^
