      @RAVerBruggen And here's when you pull out guns and then plot guns against the residuals.pic.twitter.com/xY5KPrDIb9

      @RAVerBruggen Q: To address multicollinearity (even mild) why isn't it standard to do this--remove variable of interest, use residuals?

      @RAVerBruggen When I do that, coefficient falls quite a bit:pic.twitter.com/KqytN8maJ5

      @RAVerBruggen The coefficients are not very interpretable because they are not on the same scale. You need to standardize the data.

      @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.

          @RAVerBruggen I prefer not to use Twitter as an IM. We can discuss it more, but then install TOX and add me instead. ;)
