asteroid_dens {astrodatR}

Densities of asteroids

Description

This data set gives measured values for the physical density (in grams/cm^3) of 26 asteroids in the main Asteroid Belt of our Solar System, along with their measurement errors. This dataset is useful for analysis involving heteroscedastic measurement errors in 1-dimension, such as weighted density estimation and regression. Further description and references for the dataset are given in Appendix C.1 of Feigelson & Babu (2012).
