[2] The smallest eigenvalue is 3.27e-31. This might indicate that there are strong multicollinearity problems or that the design matrix is singular. Which of the following statements are correct? a) Perfectly correlated regressors X1 and x2 are used. b) Either X1 or X2 should be excluded, as the second regressor does not add any information to the model. 6. c) The second warning indicates that the model fit to the data is perfect.
