Binary recursive partitioning analysis

WebThe supervised machine learning algorithm recursive partitioning (or "rpart" for short) is a classification algorithm that builds a decision tree model which can be used by a human being for classification. Because decision tree models are easily explainable and useable by humans, rpart is particularly useful for building tools for medical ...

Unbiased Recursive Partitioning: A Conditional Inference Framework

WebOverall survival (OS) was the primary endpoint. Multivariate analysis was performed to select the significant prognostic factors (P<0.05). A prognostic model for OS was derived by recursive partitioning analysis (RPA) combining independent predictors using the algorithm of optimized binary partition. WebFurthermore, recursive application of a statistical breakpoint analysis can generate a high resolution mapping of the bounds of localised chromosomal deletions not previously recognised. This successive decomposition of heterogeneity in differential gene expression is reminiscent of the binary recursive partitioning strategies employed in non- slow safari on iphone https://colonialbapt.org
