Declarations of Independence: How Embedded Multicollinearity Errors Affect Dosimetric and Other Complex Analyses in Radiation Oncology

Radiotherapy planning studies are a mainstay of radiation oncology research and provide meaningful guidance for both clinical decision making and radiotherapy delivery. Multivariable regression techniques are used ubiquitously in radiotherapy planning studies which are often conducted in a retrospective manner. Accurate analysis and interpretation of research data are fundamental skills for radiation oncology investigators and clinicians alike. Registrants will benefit from an accessible overview of multicollinearity errors in radiotherapy research and develop approaches to identify and manage these errors, allowing for enhanced data quality and decreased statistical bias.
