Using CART to identify prescribing thresholds for cardiovascular disease
نویسندگان
چکیده
Background and objective Many guidelines for clinical decisions are hierarchical and non-linear. Evaluating if these guidelines are used in practice requires methods that can identify such structures and thresholds. We use classification and regression trees (CART) to analyse prescribing patterns of Australian General Practitioners (GPs) for the primary prevention of cardiovascular disease. Our aim is to identify if GPs use absolute risk (AR) guidelines in favour of individual risk factors to inform their prescribing decisions of lipid-lowering medications.

Most of the land use change modelers have used to model binary land use change rather than multiple land use changes. As a first objective of this study, we compared two well-known LUC models, called classification and regression tree (CART) and artificial neural network (ANN) from two groups of data mining tools, global parametric and local non-parametric models, to model multiple LUCs. The ca...
