The horseshoe crab dataset17 Crabs3.dat at www.stat.ufl.edu/~aa

/glm/data collects several variables for female horseshoe crabs that have males attached during mating, over several years at Seahorse Key, Florida.

Use linear modeling to describe the relation between y = attached male’s carapace width (AMCW) and x1 = female’s carapace width (FCW), x2 =

female’s color (Fcolor, where 1 = light, 3 = medium, 5 = dark), and x3 =

female’s surface condition (Fsurf, where lower scores represent better condition). Summarize and interpret the output, including the prediction equation, error variance, R2, adjusted R2, multiple correlation, and model diagnostics.
