Video Code

1. Packages

library(AER)
library(MASS)
library(corrplot)

2. Data

data(HousePrices)

3. Variables

ivar <- HousePrices[, 2:5]

4. Multicollinearity

ivaricor <- ginv(cor(ivar))
colnames(ivaricor) <- colnames(ivar)
rownames(ivaricor) <- colnames(ivar)
ivaricor
corrplot(corr = ivaricor, method="number", is.corr=FALSE)
