Cluster Analysis Categories.
Canadian Medical Guide Definition Small-Area Analysis - A method of analyzing the variation in utilization of health care in small geographic or demographic areas. It often studies, for example, the usage rates for a given service or procedure in several small areas, documenting the variation among the areas. By comparing high- and low-use areas, the analysis attempts to determine whether there is a pattern to such use and to identify variables that are associated with and contribute to the variation.
Canadian Medical Guide Definition Space-Time Clustering - A statistically significant excess of cases of a disease, occurring within a limited space-time continuum.
