Through determining the conditional probabilities between different planetary types, we were able to successfully confirm a correlation between super Earths and cold Jupiters. The results on super Earths and cold Jupiters revealed that cold Jupiters are almost always accompanied by super Earths. This implies that these two planetary populations do not compete for solid material in their formation stage. The study of these correlations reveals the formation histories of planetary systems based on the types of planets present in them. In this project, we will further study the effects caused by the presence of several different planet types in these systems and provide a more complete picture.
