Heteroskedacity, serial correlation and multicollinearity

[archived_user]

Do we need to test for heteroskedacity, serial correlation and multicollinearity in level II?
Based on the learning objectives, they have only asked to”explain the types of heteroskedasticity and how heteroskedasticity
and serial correlation affect statistical inference” and to “describe multicollinearity and explain its causes and effects in
regression analysis;”.
But then i see problems at the end the chapters asking to test each of this problem

You need to know how to test for those conditions; i.e., which test uncovers which condition.
The only test you’re likely to have to perform is a Durbin-Watson test.
