Can you clarify what your looking for ? Is it more statistics on detected exoplanets to date, for which [NASA Exoplanet Archive](https://exoplanetarchive.ipac.caltech.edu/) is the best bet or a model of exoplanet formation and numbers per star etc or a model for how many exoplanet detections there should be ?

You seem to be looking for keywords like "completeness correction" and "detection bias correction". Try searching for those.

@astrosnapper Good question and link - I'm looking for a model of exoplanet formation and numbers per star that takes existing (non)detections and their probabilities into account

@AtmosphericPrisonEscape These are excellent terms! A model that would employ these is what I'm looking for

Model and statistics are different things. This question is at least on the border of too broad imho. You are asking for a review paper on explanation research and observations

# Best resource for exoplanet statistics?

(Asked by: username_0 on 2023-01-20)

While the number of detected exoplanets is still low, is there a model that, considering the number and duration of made observations, and the fact that (non)detections depend on orbital plane alignment and timing, can answer questions like

* what is the typical number of exoplanets for a star?
* what percentage of extrasolar systems can be expected to have at least one exoplanet?
* how many (Jupiter, Earth)-like planets do we expect in each solar system?
* which types of stars tend to have which types of planets?
