When fitting a multiple regression model, you should check for independence of observations and the absence of multicollinearity. Discuss how you would check appropriate statistics and/or plots. (a) When we run a multiple regression, we hope to be able to generalize the sample model to the entire population. To do this, several assumptions must be met including:  No Multicollinearity  Homoscedasticity  Independent Errors  Normally-distributed Errors Explain what is meant by each of these assumptions and describe the...
