The Kepler Mission has discovered thousands of exoplanets and revolutionized our understanding of their population. This large, homogeneous catalog of discoveries has enabled rigorous studies of the occurrence rate of exoplanets and extra-Solar planetary systems as a function of their physical properties. Transit surveys like Kepler are most sensitive to planets with shorter orbital periods than the gas giant planets that dominate the dynamics of our Solar System. I have developed a fully-automated method of discovering and characterizing long-period transiting planets with only one or two transits in the Kepler archival light curves. Since the method involves no human intervention, I can also precisely measure the completeness function of the discoveries and place constraints on the occurrence rate of exoplanets with orbital periods longer than 2 years. I will present this method and the statistical tools developed as part of this project.
