Term: High-Dimensional Propensity Score (HDPS)
Last Updated: 2015-05-12
A High-Dimensional Propensity Score (HDPS) is a probability score between zero and one typically obtained from a logistic regression model that reflects the likelihood of the outcome regressed, be it the likelihood of belonging to a group or having a disease. An HDPS is different from a propensity score in that hundreds of covariates are included in the regression model.
In Martens et al. (2015). covariates from six data dimensions were included in the HDPS regression model: diagnoses and physician tariff codes from medical claims data, diagnoses and interventions from hospital abstract data, Anatomical Therapeutic Chemical (ATC) codes from prescription drug data and survey questions from survey data.
