ex2226: Number of Moons

Description Usage Format Source References See Also Examples

Description

Apparently, larger planets have more moons, but is it the volume (as indicated by diameter) or mass that are more relevant, or is it both? These data include the diameter, mass, distance from the sun, and number of moons for 13 planets, gas giants, and dwarf planets in our solar system. Which size variable best explains mean number of moons (possible after accounting for distance from sun). (Consider negative binomial regression.)
