/*
coefficient magnitudes are quite different than the original Marvell Moody Study.
The study does not list how many of its variables are scaled, so we were liberal
with how we did the scaling ourselves. Because of this, sign and significance are
much more important than the coefficients themselves to what we are examining.

/*
Regressions with our model improvements:
-new years added in ('99-'13)
-gun production variable added
-gallup polls tested but data was sparse.. could potentially try imputing this later
