Resumen:
The Receiver Operating Characteristic (ROC) are a very well-known technique in medical studies where a continuous variable or marker (biomarker) is used to diagnose a disease or to evaluate the progression of a disease. It is common to assume that all the biomarker responses are available. However, in practical situations the missing data occur frequently such as medical research, opinion polls, etc. We are especially interested in the situation when missing responses arise and the practitioner has some covariates with predictive capability on the missingness. Under this setting, we propose two estimators of the ROC Curve using the inverse probability weighting scheme. A simulation study shows the behavior of both of them.This presentation is based on joint work with Ana Bianco, Graciela Boente and Wenceslao Gonzalez-Manteiga
