Shotgun range data
In order to test the validity of range-of-fire estimates obtained by
the application of regression analysis to shotgun pellet patterns, a
blind study was conducted in which questioned pellet patterns were
fired at randomly selected ranges between 3.0 and 15.2 m (10 and 50 ft)
with two different 12-gauge shotguns. each firing a different type
of buckshot cartridge. Test firings at known ranges were also
conducted with the same weapons and ammunition.

Shotgun range data

Usage
shotgun.df
Format
A data frame with 70 observations on 4 variables.
- range
The range in feet of the firing.
- gun
The model of shotgun used in the experiment.
- expt
A factor recording whether the data was to be used for building/training the model, or testing it.
- area
The area of the smallest rectangle that would enclose the pellet pattern.
