Selecting an agglomerative
algorithm and similarity and distance measure.
Unfortunately, the estimation does not enable us to identify specific agglomerative
forces that are at work.
hierarchical clustering can aid in this demonstration in the following way:
For that reason, this research applied CLUSTER procedure (a hierarchical agglomerative
clustering program with Ward's trace option).
Based on the way the proximity matrix is updated in step 2, a variety of agglomerative
algorithms can be designed.
Since the agglomerative
method produces increasingly large clusters, each step produces greater within-cluster variance.
In this study, the statistical technique used to create the structural taxonomies was Ward's method of hierarchical agglomerative
clustering with squared euclidean distance measures.
In the early chapters of the book, Owens relies on an intuitive principle about causal explanation to substantiate claims to the effect that coincidences cannot be causally explained and that causal explanations are neither agglomerative
We economists have our own arcane terms for labeling the powerful forces that explain these congregations, these cities: comparative advantage, economics of scale, agglomerative
Not unnaturally, the agglomerative
tendencies of similar retail outlets and the intra-centre spatial arrangement of these clusters of activity have attracted a modicum of theoretical discussion and associated empirical analysis.
instinct was reinforced by transit systems that efficiently delivered workers to a central location.
But in general the decision to draw attention to trivial parallels as well as major ones proves justified: they do have agglomerative
