A New Method for Logistic Model Assessment

Abstract

It is well known that the logistic model plays an important role for the analysis of binary outcomes. Most of the existing methods for the assessment of logistic models  are constructed based on the distance between the observed and the predicted outcomes. We consider a new method from a different perspective by assessing the distance between two consistent estimators developed under the same logistic model form.  The proposed tests are easy to implement and are applicable to both prospective and case-control studies.
