I was trying to test for multicollinearity using VIF. Here is my codes:
mreg.mod = lm(price ~ bedrooms + bathrooms + sqft_living + sqft_lot +
floors + condition + grade + sqft_basement + sqft_above
+ sqft_living15 + sqft_lot15 data = data)
summary(mreg.mod)
tidy(vif(mreg.mod))
But an error that says "there are aliased coefficients in the model" pops up. I was wondering if this has to do with my lm model?
