ex2226

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.)
