I spent too much time using my journalism-major R skills to mess with the Slate Star Codex spreadsheet, so I might as well tweet some stuff.

@KirkegaardEmil You mean the residuals of a model are on a different scale than the original variable?
@RAVerBruggen The variables in your orig. model are also not on the same scale, so beta for one not comparable to beta for another.

@KirkegaardEmil Right, but I'm just concerned about 1 percentage point change in gun ownership = X percent change in Murder -
@KirkegaardEmil That's 2.2 percent in the original model. It's not about 1 percent with the residuals? -
@KirkegaardEmil Journalism major, but I thought residuals were the difference between model prediction & actual value. How different scale? -
@KirkegaardEmil (So if model says murder's 4, actual rate is 5, the residual is 1. Both are murders/100K. Do I completely misunderstand?) -
@RAVerBruggen Residuals also take into account the intercept. -
@KirkegaardEmil Huh. Interesting, I'll have to read up on this more when I get time.
