What is the reason that ignoring the multicolinearity can be problematic when we con- struct a MLR model? One of the ways for detecting the multicolinearity is the Condition Number. What is the definition of the Condition Number and what is the difference between using correlation matrix and condition number for detecting multicollinearity?
