Opposite repertory-rubrics in Bayesian perspective.

ABSTRACT

INTRODUCTION: Hitherto entries have been added to a rubric in the repertory when patients responding well to a specific medicine showed the corresponding symptom. Continuing like this, theoretically every medicine will eventually appear in every rubric. METHOD: This becomes clear if we compare opposite symptom-rubrics. Polarity Analysis (PA) subtracts opposite rubrics and has been shown to improve clinical results. CONCLUSION: The source of this problem and the reason for the success of PA are clear from Bayesian perspective. A reliable repertory should be based on Bayesian principles.
