We present occurrence rates for rocky planets in the habitable zones (HZ) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar properties.

We show that distributing a planetary system's maximum AMD amongst its planets results in a multiplicity-dependent distribution of eccentricities and mutual inclinations.

He, Ford, & Ragozzine (2019) (arXiv:1907. 07773) applied forward modelling to infer the distribution of intrinsic architectures of planetary systems, developed a clustered Poisson point process model for exoplanetary systems (SysSim) to reproduce the marginal distributions of the observed Kepler population, and showed that orbital periods and planet radii are clustered within a given planetary system.

We find that the Kepler dichotomy is evidence for a population of highly-inclined planetary systems and is unlikely to be solely due to a population of intrinsically single planet systems.

We characterize the occurrence rate of planets, ranging in size from 0. 5-16 R$_\oplus$, orbiting FGK stars with orbital periods from 0. 5-500 days.

From these probabilities, we predict that $25. 5^{+0. 7}_{-0. 7}$ of the known RV exoplanets should transit their host stars.

For orbital periods less than 100 days the Robovetter completeness (the fraction of simulated transits that are determined to be planet candidates) across all observed stars is greater than 85%.

For 779 KOIs with high enough SNRs, we derived the timing, duration and depth of 69, 914 transits.
