In the sense of this distance measure, two clusters are close when all subjects in both clusters are close.
Our structured sampling design consisted of a combination of three transects with five measuring points and four clusters with three measuring points (i.e. a total of 27 points).
The ergonomic measures are defined in four clusters: 1) mechanical measures for horizontal or vertical transportation, such as a crane, 2) ergonomic measures for raising equipment or materials, such as a raised mortar hod, 3) ergonomic measures to adjust working height on the worksite, and 4) ergonomic handtools.
Bi-plot analysis of stability measures revealed that stability measures can be distributed into four clusters (Fig. 3): (1) biomass, pH and SAR, (2) TN, TP and Na, (3) Ca2+· + Mg2+ alone and (4) CO3 2− + HCO3− and E.C.
Davies-Bouldin (DB) makes use of similarity measure (R_{ij}) between the clusters (C_i) and (C_j), which is defined upon a measure of dispersion ((s_i)) of a cluster (C_i) and a dissimilarity measure between two clusters ((d_{ij})).
The structural distance measure between two clusters and is defined as.
As with the ability to use, the facilitation of each of four clusters of ergonomic measures will be assessed.
Considering these four clusters as composite measures of the 18 symptoms, the variance explained by individual symptoms within a cluster was reassessed.
The four clusters of proxy measures for DA dysfunction (bipolar symptoms, prolactin-related adverse effects, EPS and use of antipsychotics) were individually included as independent variables in the Cox models in order to determine associations with incident TDD.
And so, if I go back to 1984, there are roughly four clusters when I measure each quarter and I take the next year's return.
