The model included a random intercept allowing for clustering of measures within individual, and a random slope for the linear term of age allowing person-specific age slopes to be determined.
Pardos et al. (2014) Clustering To measure the similarity of individuals described by data.
Each of the observed cluster of measures has been given an intuitive "group" name to simplify the general pattern.
The resulting PCA shows the major dimensions along which the abstract notion of scientific impact can be understood and how clusters of measures correspond to similar aspects of scientific impact.
Equally, Wilkinson identifies five clusters of measures of professionalism, one of which clearly correlates with conscientiousness, and the other four may well represent different aspects of professionalism [ 2].
Learning from other international casemix models and benchmarking data sets, the UKROC team has developed a cluster of measures to inform the development of effective and cost-efficient rehabilitation services.
However, as noted above, the FIM has some limitations in both of these roles, so the UKROC team has developed a cluster of measures which are intended to provide more directly the information that service providers and planners require to develop effective and cost-efficient rehabilitation services, sensitive to the needs of their local population.
As a consequence, the "glucose triad" could be translated for clinical purpose into the trilogy of "sevens" (Fig. 2) that integrates a cluster of measures, including diagnosis (≥7 mmol/l glucose at fasting), interventional threshold values for completing treatment: A1C goals <7% and postprandial glucose targets <7 mmol/l at 2-h after lunch.
The silhouette statistics have been used to assess the quality of clustering by measuring how well an object is assigned to its corresponding cluster.
Kettritz et al. [20] in a trial involving 2,874 patients in five centres using 11-G VAB removed 76% of clusters measuring less than 10 mm and even removed 30% of clusters measuring 11-20 mm in diameter.
