Recursive partitioning

Recursive partitioning is a statistical method for multivariable analysis.[1] Recursive partitioning creates a decision tree that strives to correctly classify members of the population based on several dichotomous independent variables.

This article focuses on recursive partitioning for medical diagnostic tests, but the technique has far wider applications. See decision tree.

As compared to regression analysis, which creates a formula that health care providers can use to calculate the probability that a patient has a disease, recursive partition creates a rule such as 'If a patient has finding x, y, or z they probably have disease q'.

A variation is 'Cox linear recursive partitioning'.[2]

Advantages and disadvantages


Compared to other multivariable methods, recursive partitioning has advantages and disadvantages.

Examples

Examples are available of using recursive partitioning in research of diagnostic tests.[6][7][8][9][10][11] Goldman used recursive partitioning to prioritize sensitivity in the diagnosis of myocardial infarction among patients with chest pain in the emergency room.[11]
