The Transit Timing Variation (TTV) has known to be a useful tool for exoplanet detection, studying planetary orbits, and addressing the configuration of multi-planet systems. In order to further understand the nature of the systems observed by the Kepler Space Telescope, we try to model their observed TTV. Both analytic and numerical models will be employed to fit the TTV data through MCMC sampling. Through this process, the orbital parameters could be determined and the structures of these systems might be revealed.
