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)
